Probiotics may sound like just another of the many available supplements, but probiotics are unique because they are alive. Probiotics are a collection of live bacteria and yeast beneficial to the digestive system. These microorganisms are considered “good” bacteria and work hard to keep your cat’s gut balanced and functioning efficiently.

If you browse the pet store or your local vets, you’ll find a range of commercially produced probiotics that you can easily add to your cat’s diet. But if you are looking for a way to boost your cat’s probiotic count naturally at home by making homemade cultures to supplement their diet, then you’ve come to the right place.

We have collected three recipes for homemade probiotic foods that you can give to your cat as well as to yourself!

The 3 Top Recipes of Homemade Probiotics for Cats

1. Coconut Kefir

Coconut Kefir for Cats

Coconut kefir is delicious! And this recipe is super easy to make.

Equipment

  • 1 glass jar and lid must be sterilized by boiling
  • 1 wooden or plastic spoon

Ingredients
  

  • 1 coconut's water
  • 1/2 tbsp water kefir grains

Instructions
 

  • Rinse the kefir grains with drinking water
  • Add the kefir grains into the glass jar
  • Cover keffir grains with coconut water
  • Place the lid and close the jar
  • Set inside the counter or in a dark place. The ideal temperature must be between 75-85°F (24-30°C) Light and temepratures outside of this ranges should be avoided.
  • Wait 12 hours and use a sterile plastic spoon to taste the product it should had a yogurth-like taste. If it does not taste like yogurth place back in the conter and give it 12 hours more.
  • Carefully strain the kefir granules out using a wooden spoon. If you intend to keep them for future fermentations place them in another sterile container and cover them with purified water and sugar.
  • Cover your coconut kefir and keep it inside the fridge.

Notes

  • You can start by giving the cat 1/4 tsp of this batch twice a day for 5 days.
  • You must prepare a new batch after the 5th day. You can drink the remaining of this water!
  • You can gradually increase the amount to 1/2 tsp then to 1 tsp twice a day

We recommend starting with small amounts 1/4 tsp once a day and observing the cat, then gradually increasing to 1/2 tsp twice a day. With time you can work your way up to give 1 tsp twice a day. The coconut water kefir that is more than 5 days old should not be given to your cat, however, it is safe for you to drink. Do not add sugar, fruits, or honey to this recipe, and please make sure you rinse the kefir granules very well before each new batch.


2. Milk Kefir

This first one may be odd to you initially, as it is pretty common knowledge now that most cats are actually lactose intolerant.  Cats lack the enzyme “lactase” to properly digest lactose in milk and other dairy products.

The fermenting process of kefir milk eliminates much of the lactose found in the milk, and when producing it for cats, it’s recommended to use goat’s milk and twice ferment the product, this will result in an almost lactose-free product.

This recipe from Authentica Pets is the ultimate guide for crafting kefir, even offering up milk-free versions and optional additives to increase the taste for your cat. They crown kefir as a “super” probiotic as it contains over 50 strains of bacteria.

This recipe is our top pick as it is likely to be the one that your cat likes the most! Cats are not as interested in plant-based food items due to their carnivorous diet, but dairy products are often savory enough to attract them.


3. Honey Berries

This recipe is super simple if you aren’t interested in crafting a complicated and multistep probiotic. Boulder Holistic Vet has this great recipe for fermented honey-berries that involves a simple fermentation process.

This recipe can be ready within 24 hours if you already have the right ingredients. The ingredient list is limited, but it does involve sourcing a culture starter, which is not the most common household ingredient!

While fruits, such as berries, aren’t a part of a cat’s diet, they offer some additional benefits when given as a small treat. This recipe, of course, offers a range of healthy probiotics, but it also has the extra antioxidants of blueberries. Blueberry powder is sometimes used as an ingredient in pet food for its “superfood” status.

The addition of honey also acts as a great anti-inflammatory and supports your cat’s immunity.


The Benefits of Probiotics for Your Cat

Like us humans, your cats’ digestive tract contains millions of microorganisms. Probiotics are considered the “good” bacteria in the gut. They service the body by fighting off the “bad” or harmful bacteria.

These good bacteria exist naturally in your cat’s digestive system. Still, various reasons can cause the good bacteria to lose out to the harmful bacteria and put your cat at risk of becoming ill.

Probiotics can be beneficial to cats of all ages and all health conditions, but they may be especially helpful for cats who are:
  • Elderly
  • Sick
  • Have recently been on antibiotics (while the medical goal is to eliminate pathogens, they kill all the good bacteria as well)
  • Suffering from stomach upset
  • Under stress
  • Immunocompromised
  • Frequently have hairballs
  • Not eating the correct diet
  • Suffering from internal parasites

All the above conditions can throw out the natural and delicate bacteria balance in your cat’s gut. The result can be seen as a stomach upset, food intolerances, and diarrhea, to name a few. Additionally, an unbalanced gut can put your cat at higher risk of contracting illnesses or infections. The gut microbiota plays a very important role in your cat’s immunity, and the colonization of beneficial bacteria competes against many opportunistic bacteria that given the chance could turn into pathogens causing infection. In simple words, they do not allow the bad guys to take over and reproduce.

Probiotics vs. Prebiotics

If you’ve heard of probiotics, then you’ve probably heard of prebiotics, and you wouldn’t be the only one if you assumed they were the same thing! However, this is not so. Probiotics are living microorganisms of yeast and bacteria. Alternatively, prebiotics are simply plant matter that is the food source of probiotics.

Prebiotics nourish the natural probiotics in your cat’s gut allowing them to thrive. Probiotics can be super beneficial on their own, but blustered with prebiotics, they can grow more easily, reproduce and colonize in your cat’s gut

Homemade Probiotics for Your Cat

There is a range of probiotic supplements on the market for your cat.  Many of these are concentrated and in powder or treat form, and they also tend to be expensive! Additionally, many complete cat diets will have probiotics added.

If you want to add more probiotics to your cat’s diet and give them a natural supplement, using any of the above homemade probiotic recipes may be helpful for you.

Final Thoughts

Whether you’re looking for a probiotic boost to your cat’s kibble, or a probiotic source for your homemade raw cat diet, we recommend you consult your vet for guidance on homemade probiotics. Once given the all-clear, why not give some of the above recipes a go? If your cat doesn’t like them, they are all safe for you to eat!
