The 10 Best Cat Foods for Diarrhea in Canada
1. Hill’s Science Diet Sensitive Stomach Cat Food — Best Overall
|Main ingredients:||Chicken, brewers rice, corn gluten meal, whole-grain corn|
Hill’s Science Diet Sensitive Stomach is our number-one choice for the overall best cat food for diarrhea in Canada. This easily digested recipe includes prebiotics to improve your cat’s digestive health and make it easy for them to absorb the nutrients from their meals. This food is also commonly recommended by veterinarians for cats with sensitive stomachs.
The downside to Hill’s Science Diet cat food is the cost. It’s more expensive than most box store brands, but it has the quality nutrition that you would expect from prescription food.
2. Blue Buffalo Sensitive Stomach Cat Food — Best Value
|Main ingredients:||Deboned chicken, chicken meal, brown rice|
Blue Buffalo Sensitive Stomach is the best cat food for diarrhea in Canada for the money. It’s made with all-natural ingredients and no preservatives. You can feel good about offering this quality nutrition, soothing your cat’s digestive upset, and spending less on cat food.
This recipe is formulated with specific nutrients to support your cat’s heart, eyes, digestion, immune system, and skin and coat. It also has an appropriate calorie level to help with weight management.
While Blue Buffalo cat food is relatively easy to find, this sensitive stomach recipe isn’t. You’ll likely have to order this food online, making it less convenient than most other options.
3. Purina ONE Sensitive Systems Cat Food — Premium Choice
|Main ingredients:||Turkey, chicken by-product meal, rice flour|
Purina ONE Sensitive Systems uses turkey as the number-one ingredient in this recipe, so it’s a great choice if your cat has a sensitivity to chicken. This high-protein food maintains your cat’s lean muscle mass, but it’s also easy to digest.
The downside of Purina ONE is that it’s more expensive than most other brands. However, if your cat is struggling with diarrhea, customer reviews show that this food offers better diarrhea control than many other foods. While many brands target vomiting and diarrhea in their sensitive stomach recipes, Purina ONE specifically addresses diarrhea.
4. Royal Canin Kitten Food
|Main ingredients:||Water, pork by-products, chicken, chicken liver|
If you’ve got a kitten with diarrhea, you need food that addresses their tummy issues and still provides quality nutrition for young, growing cats. Royal Canin Feline Health Nutrition Kitten Food meets both criteria. It has easy-to-digest proteins to solve your cat’s diarrhea problem and includes all the vitamins and nutrients needed for healthy growth and development.
This is wet food, so it’s less cost-effective than dry kibble. Ideally, it should be paired with Royal Canin’s dry kitten food.
5. Hill’s Science Diet Perfect Digestion Cat Food
|Main ingredients:||Salmon, brown rice, corn gluten meal|
Our next choice of cat food for diarrhea is Hill’s Science Diet Perfect Digestion. This recipe is slightly different than Hill’s Sensitive Stomach recipe and specifically targets gut health and digestion. It’s nutritionally complete and easy to find without needing a prescription. The bag even claims that your cat will have “perfect poop” in 7 days with this food, which suggests that it’s incredibly effective at solving diarrhea issues.
As with other Hill’s foods, this one is expensive. It also has a flavour that many cats don’t like, and it may take your kitty a while to adjust to eating this recipe.
6. Halo Holistic Sensitive Stomach Cat Food
|Main ingredients:||Whitefish, salmon, dried egg product|
Halo Holistic Sensitive Stomach is carefully balanced to reduce food intolerances and improve digestion. Halo claims to be a holistic, clean cat food company, so this food has no contamination or unnaturally raised ingredients. Halo goes above and beyond to ensure that you are getting real ingredients. Unfortunately, this also makes its food more expensive than most other brands.
Picky cats love the taste of Halo Holistic food, though, so it’s a good choice if you’re having trouble getting yours to eat. Customer reviews also indicate that it does a good job of reducing both diarrhea and vomiting episodes. The litter box is also less smelly overall, which is something that every cat owner can appreciate.
7. Royal Canin Feline Health Sensitive Digestion Cat Food
|Main ingredients:||Chicken by-product meal, chicken fat, corn gluten meal|
Royal Canin Feline Health Sensitive Digestion has many options for cats with sensitive digestive systems. This one contains easily digested ingredients and prebiotics to promote healthy gut flora. This recipe’s kibble shape is unique to encourage your cat to eat. The nutritional quality of this recipe is concentrated, so you can feed your cat small portions. This makes this variety more cost-effective and easier to feed to picky cats, as you don’t have to give them as much.
Royal Canin Sensitive Digestion seems to fix digestive issues for some cats but create them in others. The kibble also has an oily coating that some cats refuse to touch.
8. Earthborn Holistic Primitive Feline Cat Food
|Main ingredients:||Turkey meal, chicken meal, peas|
Earthborn Holistic Primitive Feline Grain-Free Cat Food is a grain-free option for cats with diarrhea. It includes all-natural, quality ingredients like spinach, cranberries, carrots, blueberries, and apples. The high protein content comes from all-animal sources to maintain your cat’s muscle mass.
This recipe targets the health of your cat’s skin and coat and their immune system. As a bonus, Earthborn Holistic’s packaging is resealable and 100% recyclable.
While this food resolves diarrhea in many cats, it’s not specifically for sensitive stomachs. Serious cases may require a prescription diet food.
9. Royal Canin Feline Care Digestive Care Cat Food
|Main ingredients:||Brewers rice, wheat gluten, chicken meal, chicken fat|
Royal Canin Digestive Care is a prescription food for sensitive stomach and digestive concerns. It’s specifically formulated to control diarrhea, vomiting, and hairballs.
The prebiotics and high fiber levels promote easy digestion. The kibble is ring-shaped, which is meant to slow down digestion and therefore help your cat absorb as many nutrients as possible from the food. The company claims that 10 days on this food will produce 42% fewer stools for your cat.
Since this is a prescription food, it is more expensive than most other brands. It also tastes a bit different, so it can be hard for picky cats to get used to the flavour.
10. Purina Pro Plan Focus Sensitive Stomach Cat Food
|Main ingredients:||Lamb, rice, corn gluten meal|
Purina Pro Plan Focus Sensitive Stomach offers a novel protein option for cats with sensitive stomachs and skin. It’s rare to see a sensitive digestion cat food that doesn’t use chicken as the primary protein. This recipe contains easy-to-digest ingredients to promote overall gut health.
The kibble in Purina Pro Plan cat food is softer than you might expect, so its appeals to picky cats and those with mouth or dental issues.
The downside of this food is that you will go through quite a large amount of it, so it’s less cost-effective overall.
Buyer’s Guide: How to Pick the Best Cat Food for Diarrhea
What Is Diarrhea?
Diarrhea in cats is similar to what it is in humans: watery, loose stools. Sometimes when cats have diarrhea, they will use the litter box more frequently.
Usually, diarrhea is a result of food moving through the digestive tract faster than it should. This means your cat is absorbing fewer nutrients from their food. This is also why most foods for cats with diarrhea are designed to slow down the digestive process.
The causes of diarrhea can vary and include viruses, bacteria, worms, or sensitivity to certain foods. It’s important to monitor your cat’s litter box trips, including how often they’re going, how long they have had diarrhea, and if the diarrhea is constant or a one-off episode.
When to Be Concerned
Cat’s bowel habits can change from time to time, and it’s important to note whether your cat has a one-off episode of diarrhea or if they have diarrhea every day. Much like humans, cats can have episodes of loose stools that aren’t a cause for concern. They may have eaten something that they shouldn’t, it’s hot out and they’re overheated, or they just aren’t feeling well. If it clears up on its own, it probably doesn’t warrant a rush visit to the vet.
If your cat has regular diarrhea, you need to get their bowel habits back to normal. It’s a good idea to have them see the vet to make sure there isn’t a bigger problem. They may be given a dewormer to ensure that that isn’t the problem.
The biggest concern with chronic diarrhea in cats is dehydration. When diarrhea persists, cats lose important nutrients and water. Sometimes this can be corrected by giving them wet food or extra water to drink; other times, it requires veterinary intervention.
Diarrhea is often caused by the food that your cat consumes. Sometimes it’s because they ate something that they shouldn’t have or because their food is changed too quickly and their system has trouble adjusting. Other times, it’s the ingredients in the cat food.
Switching to a gentle food designed to alleviate digestive upset can help you determine if food is indeed the cause.
