The 9 Best Cat Supplements
1. Nutri-Vet Multi-Vite Salmon Flavored Gel Multivitamin For Cats – Best Overall
| Supplement type | Gel |
| Life stage | All |
| Vitamins | A, B12, C, D2 |
Nutri-Vet Multi-Vite Salmon Flavored Gel Multivitamin For Cats is our choice as the best available vitamin and supplement for cats because it not only offers a good range of essential vitamins and minerals, but it also comes in a convenient and palatable gel.
It’s up to you how you give the gel. Some cats will lick it directly from a finger, thanks to the natural fish flavors. Alternatively, you can mix it in with some wet food, or, for especially picky and selective diners, you can put it on the paw and the cat will clean or lick it straight off.
The gel contains vitamins B12, B6, and B2, as well as vitamin C and omega fatty acids. It is also fortified with calcium, zinc, and copper, and is rounded off with a natural salmon flavor to make it more appealing. The gel can be given to cats of all ages, but you should seek veterinary advice before giving it to a poorly cat, or one that is taking other medications.
Although it is a good all-round product, the gel can be flicked off paws, and some cats are put off by the smell.
- Includes vitamins A, B, C, and D
- Gel is easy to administer
- Good price
- Gel can be flicked off paw without eating
- Strong smell might deter fish haters
2. Pet Naturals Daily Multi Cat Chews – Best Value
| Supplement type | Chews |
| Life stage | All |
| Vitamins | A, B, C, D, E |
Pet Naturals Daily Multi Cat Chews are soft chewable tablets that can be given to kittens and seniors, as well as adult cats. They contain a full complement of vitamins A, C, D, E, and B complex vitamins, as well as calcium, magnesium, and phosphate minerals.
The ingredients include fish meal, designed to make the chews more appealing and tastier for your feline friend, and the cost of the chews is very reasonable, making them the best vitamins and supplements for cats for the money. Despite the inclusion of fish meal, the chews seem to smell more like tablets and won’t appeal to all cats. Also, unless yours really likes the smell or is an inquisitive cat that investigates everything using its mouth, it can be difficult to persuade a cat to eat chewable tablets.
The soft, chewable texture does mean that Pet Naturals can be given to kittens and senior cats, including those with dental problems, as well as adult cats.
- Suitable for kittens, adults, and seniors
- Contains a full complement of essential vitamins
- Cheap
- They have a strong smell
- Not all cats will easily chew tablets
3. Rx Vitamins Rx B12 Liquid Digestive Supplement for Cats & Dogs – Premium Choice
| Supplement type | Liquid |
| Life stage | Adult |
| Vitamins | B12 |
Vitamin B12 is vital to immune health and supports the nervous system and digestive system. It helps maintain cognitive function. If you have been advised that your cat is deficient or if you are looking for a supplement that might help with an upset stomach problem, a B12 supplement could offer the solution, especially as cats are unable to produce their own vitamin B12.
Rx Vitamins B12 Liquid Digestive Supplement For Cats & Dogs contains cyanocobalamin, which is a synthetic B12 and not a natural solution. It is a liquid and comes in a dropper bottle. The supplement also has natural flavorings designed to make them easier to give to your cats. Give a single drop every day, typically done by adding it to food.
Although this supplement is expensive, a single bottle provides enough drops to last 3 to 4 months. It can also be given to dogs, which means that it won’t last as long but offers the same benefits to canines as to felines.
- Easy to administer a single drop
- Contains enough for 3 months
- Can be given to dogs too
- Expensive
- Contains fructose
4. Tomlyn Felovite II Gel Nutritional Supplement For Cats – Best for Kittens
| Supplement type | Gel |
| Life stage | All |
| Vitamins | A, C, E, taurine, calcium |
Tomlyn Felovite II Gel Nutritional Supplement For Cats is a gel multivitamin that can be fed directly, disguised in wet food, or applied to the paw so that your cat licks it off naturally. It contains vitamins A, C, and E, as well as calcium and taurine. Unlike most mammals, cats are unable to synthesize enough taurine to meet their needs, which means that it is an essential vitamin. Essential vitamins are those that an animal needs but must get from its diet. While some commercial foods are fortified with added taurine, this may not be enough for your feline’s requirements, and still, not all foods have it added.
As well as being an easily administered gel, this nutritional supplement for cats has a fish flavor that should make it more appealing, as long as your picky eater likes fish. However, as with most feline supplements and even foods, some picky eaters will still turn their noses up, and it would perhaps benefit from a stronger smell or different aroma.
Tomlyn is not only suitable for seniors and adults but also for kittens, so it is a good way of ensuring that your young furball is getting all the B12 it needs. Administering to kittens also gives you and your cat the chance to get used to giving it.
- Contains vitamins A, C, E, and taurine
- Gel is easy to administer
- Reasonable price
- Fishy smell not enough to attract all cats
5. VetriScience NuCat Senior Soft Chews Multivitamin For Cats – Best for Seniors
| Supplement type | Chews |
| Life stage | Senior |
| Vitamins | A, B12, D, calcium, taurine |
Senior cats have different dietary and health requirements to adult cats and kittens. This is especially true for house cats. Although they do not synthesize vitamin D from the sun in the same way as people, cats benefit from time outdoors primarily because of the amount of exercise they get. Even the most playful and energetic of indoor cats will not get the same level of exercise.
VetriScience NuCat Senior Soft Chews Multivitamin For Cats are soft, chewable multivitamins that are administered daily and formulated specifically to aid indoor, senior cats, typically referring to cats aged 11 or older that are showing signs of aging.
Taurine is an essential vitamin that cats need to get in their food and, as well as containing this often-overlooked vitamin, the VetriScience NuCat formula also includes vitamins A, B12, and D. The supplement comes in a soft, chew form, which means that even cats with poor dental health and sensitive teeth can eat. However, while the chews are soft, not all cats will eat a chewable tablet, and these are quite large so some senior cats will be deterred.
- Soft and chewable tablets
- Formulated specifically for senior, indoor cats
- Contains taurine as well as vitamins A, B12, and D
- Not all cats will take chewable tablets
- The tablets are large and non-uniform in size
6. Purina Pro Plan Veterinary Diets FortiFlora Powder Digestive Supplement For Cats
| Supplement type | Powder |
| Life stage | All |
| Vitamins | Probiotics |
Probiotics are live bacteria that are found in some foods and supplements. They are given to cats and can aid in good digestive health and support the immune system while maintaining good general health.
Purina Pro Plan Veterinary Diets FortiFlora Powder Digestive Supplement For Cats is a powder formula, which means that it can be mixed with wet food or a tasty treat to make administration easy. Different types of probiotics benefit cats in different ways, and the ones in FortiFlora are specifically geared towards helping cats that suffer from diarrhea. It also contains brewers’ yeast which is believed to help tackle and prevent flea infestations. Liver flavor makes it more appealing to finicky felines.
The supplement can start to have some positive effects within the first few days, but you should expect the best results after about 2 weeks. The Purina supplement is expensive, and you have to feed a full sachet to ensure that the probiotics are making it where they need to go. Plus, the liver flavor is quite pungent and may deter some cats.
- Can help combat diarrhea
- Brewers’ yeast can help combat fleas
- Powder formula is easy to feed
- Expensive
- Falvor doesn’t appeal to all
7. NaturVet Kelp Help Plus Omegas Powder Supplement For Cats & Dogs
| Supplement type | Powder |
| Life stage | All |
| Vitamins | Omega fatty acids |
NaturVet Kelp Help Plus Omegas Powder Supplement is made from dried kelp and fortified with additional vitamins and minerals. It comes in a powder form, which should make it easier to administer to even the most difficult of pets, and it is specifically formulated to provide delivery of omega-3, -6, and -9 fatty acids. This formulation helps maintain good digestive health and also manages the health of your cat’s coat and skin.
Cats are usually very precise about their appearance. They aren’t overly keen on getting dirty and spend a lot of time caring for their own coat. As such, if you see signs that their fur is looking tired and old, it is a good sign that they need supplementation or some other form of intervention to help bring their fur back to its best.
NaturVet Kelp Help Plus Omegas Powder Supplement is quite expensive and while a powder supplement can be easy to give to good eaters, picky eaters will smell it on their food. As well as being suitable for cats of all ages and in all life stages, you can also give it to dogs.
- Powder is easy to administer
- Contains omega fatty acids for coat health
- Picky cats might avoid the smell
- Quite expensive
8. Animal Nutritional Products UroMAXX Urinary, Kidney & Bladder Dog & Cat Supplement
| Supplement type | Liquid |
| Life stage | All |
| Vitamins | Vitamin C |
Animal Nutritional Products UroMAXX Urinary, Kidney & Bladder Dog & Cat Supplement is a liquid supplement made from cranberry juice, vitamin C, and a blend of herbal extracts. It is specifically designed to prevent and aid urinary, kidney, and bladder infections.
It can be used to treat conditions including urinary tract infections, cystitis, and hematuria as well as other related conditions. Animal Nutritional Products claims that UroMAXX is the only liquid supplement to treat urinary tract conditions. Because it is a liquid it can be poured over or mixed into food, although this is a very viscous solution, so it can be difficult to mask and mix. The natural chicken flavor does help to make it easier to get down your cat, although there are some reports that it has a strong flavor that puts cats off.
Although it is quite an expensive product, UroMaxx serves a specific purpose, and if your cat suffers urinary infections and other kidney and bladder-related conditions, it could help.
- Can combat and prevent urinary infections
- Liquid can be mixed in with food
- Expensive
- Thick liquid is difficult to mix
9. Rx Vitamins Rx D3 Liquid Immune Supplement
| Supplement type | Liquid |
| Life stage | Adult |
| Vitamins | D3 |
Rx Vitamins Rx D3 Liquid Immune Supplement is a liquid supplement that provides vitamin D3 to your cat.
Cholecalciferol, also known as vitamin D3, is a fat-soluble vitamin that is considered essential to cats. It is stored in the fat cells in the body, so if your feline friend is getting a decent intake of it through food and other sources, it shouldn’t suffer a deficiency.
Humans get vitamin D from sunlight. Our skin naturally absorbs the vitamin directly from the sunlight and delivers it to our body. Cats have much thicker skin, and the skin cannot naturally absorb the vitamin the same way as humans do. Their skin does still create vitamin D3, and they ingest it when licking and preening their fur. This means that even indoor cats create some vitamin D3 from their skin when they sit on the windowsill or collapse in the last sunny spot in the corner of the room, but they may need help ensuring that they get enough of it.
Rx D3 is a liquid so can be mixed in with food or syringed into the mouth. It only delivers a relatively small amount of vitamin D3 per drop, however, which means that this supplement may not be strong enough for a seriously deficient cat.
While vitamin D plays an important role in calcium absorption, muscle movement, and immune and nervous system functions, excessive amounts of Vitamin D may result in poisoning. Please only supplement your cat in the cases and amounts prescribed by the veterinarian.
- Tops up vitamin D3 in your cat
- Liquid form is easy to mix with food
- Expensive
- A relatively mild dose of vitamin D3
Buyer’s Guide: Selecting the Best Supplements for Your Cat
Supplements and multivitamins serve the same purpose for cats as they do for humans. They provide vitamins and minerals that a cat requires and that, for one reason or another, they do not get enough of in their diet.
It is a good idea to check with a vet before introducing a new vitamin or supplement to your cat’s diet, but if your feline friend has a deficiency in a certain vitamin or you have been advised to offer a regular supplement, finding the right one is important. This means checking ingredients, determining the required level of the vitamin in question, and ensuring that it is palatable and easy enough to administer. Every cat is different, so while a particular supplement might be a good choice for one cat, there might be something better for another.
Supplement And Vitamin Types
It is possible to buy supplements for almost any essential vitamin and mineral, but most fall into the following categories:
- Multivitamins – As the name suggests, multivitamins provide an array of different vitamins. There is no specific or precise classification of what qualifies as a multivitamin, and while some are quite limited in the vitamins that they do offer, others have the full complex. Multivitamins are convenient and can be used to fortify your cat, prevent them from getting ill or becoming rundown, and they can also help if your cat is low in several vitamins. They are especially useful for very picky eaters that are perhaps not getting enough vitamins in their diet.
- Vitamin B12 – Cats cannot produce vitamin B12 themselves, but it is essential for their good health, which means that it is classified as an essential vitamin and must come from a dietary source, such as food or supplementation. It supports the digestive system, immune system, and nervous system, while also helping to maintain good cognitive functions. This vitamin is found in meat and liver. A diet that is lacking in substantial amounts of meat can cause a deficiency. Vitamin B12 requires multiple organs to help digest and use it, so any organ failure or illness can also lead to problems and require supplementation. Some cats are given vitamin B12 injections, but the body only retains vitamin B12 for a limited time, so injections need to be regular. Supplements can be given daily and may act as a cheaper, more convenient and healthier alternative.
- Vitamin D – The skin of cats, like humans, produces vitamin D when in the sunshine. However, whereas human skin naturally absorbs the vitamin D, cats have thicker skin and are covered in fur that prevents this from happening. They get a fraction of the vitamin D they require from their diet, but the majority of a feline’s vitamin D intake will come from licking their fur. Because vitamin D is fat-soluble, any excess remains in the body and is not disposed of through urine. Vitamin D poisoning is possible if you don’t carefully monitor and check the levels your cat is getting. Follow a veterinarian’s advice or the manufacturers’ instructions to ensure safe levels are given.
- Omega Fatty Acids – Omega fatty acids reduce inflammation which, in turn, can reduce the pain caused by diseases like arthritis. They are also good for the skin and ensure the optimal condition of a cat’s coat. Cats require more DHA than EPA, which contrasts with dogs, so if you are buying omega fatty acid supplements, try to ensure that they are geared towards cats. Some high-dose fatty acid supplements can give cats diarrhea and cause vomiting so don’t overfeed.
- Probiotics – Probiotics are live bacteria that fight the bad bacteria in your cat’s gut. There are many types of probiotics, and each type offers its own benefits and use. When buying probiotic supplements, check what benefits they are purported to offer so that you can be sure you are buying one that is relevant to your cat’s needs.
Supplement Form
As well as considering the actual vitamins and minerals that supplements offer, you should ensure that your cat will take them. Cats are notoriously difficult to give pills to, and they can be very picky eaters, turning their noses up at anything that seems different or unusual in their food. You will know what is likely to work best for your cat, but most cat vitamins come in the following forms:
- Liquid – Liquid supplements are easy to deliver. If your cat is eager, and if the liquid has a good aroma and taste, you may simply be able to drop a drop in their mouth. Alternatively, you can mix it in with their wet food. You shouldn’t add it to their water, because it could put them off drinking. Check what other ingredients are used in the supplements and the process that was used to convert to a liquid.
- Gel – Gels are also increasingly common and might be referred to as paw gel. This is because one of the ways that a gel can be administered is to put it on the cat’s paws. The cat will either clean it off or lick it off to enjoy the taste. In either case, the gel is digested, and the vitamins can do their work. Gel can also be mixed with wet food.
- Powder – Powder supplements are a very fine powder. The only way to really administer a powdered supplement is to mix it in with wet food. Make sure it is thoroughly mixed, or your cat may notice the alien ingredient and leave the food.
- Tablets – If you have a very accepting cat, or a pill popper, tablets are an option. They are convenient because they are uniformly sized and they keep in the bottle, but very few cat supplements are available in this form because of how difficult they are to give.
- Chews – Chews or soft chewable tablets are similar in consistency to a piece of chewable gum. Because they are soft, they are considered suitable for senior cats and those with sensitive teeth and gums. Not all cats will readily take and eat a chew, even if it is soft and laced with liver flavor, however.
Final Thoughts
Vitamins and supplements for cats can support your cat’s health and ensure they stay fit and healthy. They can help combat vitamin deficiencies and can be used to overcome problems like diarrhea and vomiting. They take various forms and serve many purposes, which means there is a wide array of choices. Hopefully, our reviews have helped you select the supplement that is best for your cat.
We believe Nutri-Vet Multi-Vite Salmon Flavored Gel Multivitamin is the best available supplement because it is relatively inexpensive, the gel is easy to administer, and it has a good range of vitamins that your cat needs. For a tighter budget, Pet Naturals Of Vermont Daily Multi Cat Chews are affordable and effective, as long as you can convince your cat to take them.
