| Main ingredients: | Chicken, chicken broth, chicken liver |
| Protein content: | 10% |
| Fat content: | 6% |
| Calories: | 199 kcal/can |
The overall best cat food for constipation in Canada is Blue Buffalo’s Healthy Gourmet Natural Pâté Cat Food. It has high-quality protein with real chicken and includes healthy ingredients but no fillers, artificial flavours, or preservatives. It’s high in soluble fibre from guar gum and flaxseed, which can help the motility of a constipated cat. It’s also low in carbohydrates.
The cons are that it is pricey and high in fat. Also, if your cat isn’t a fan of pâté, they might not like this one.
- High-quality protein with real chicken
- Natural ingredients
- No artificial ingredients or fillers
- High in soluble fibre, including flaxseed
- Pricey
- Only in pâté
- High in fat
2. Iams Perfect Portions Healthy Adult Cat Food — Best Value
| Main ingredients: | Chicken, water poultry liver |
| Protein content: | 9% |
| Fat content: | 5% |
| Calories: | 45 kcal/serving |
The best cat food for constipation in Canada for the money is Iams Perfect Portions Healthy Adult Wet Cat Food. This one is ideal for cats that need a diet low in fibre because sometimes, too much fibre can lead to constipation. It’s grain free and contains simple ingredients in a tasty pâté. It comes in small single-serve trays that you just peel and dish out for your cat. No leftovers need to go in the fridge.
However, the packaging isn’t entirely environmentally friendly, and it’s fairly high in fat.
- Well-priced
- Moderate amount of fibre
- Grain-free with simple ingredients
- No leftovers with single peel-and-serve trays
- Not completely environmentally friendly
- Fairly high in fat
3. Weruva Best Feline Friend Variety Pack — Premium Choice
| Main ingredients: | Tuna, fish broth, chicken |
| Protein content: | 12% |
| Fat content: | 2% |
| Calories: | 69 kcal/can |
Weruva’s Best Feline Friend Variety Pack is our pick for premium choice cat food for constipation. This is a canned food that’s low in fibre and carbohydrates. It’s quite high in protein, with several high-quality ingredients, but is only moderate in fat. It also has a high moisture content, which can be helpful for constipated cats. This is also a variety pack with four recipes, one of which contains pumpkin, a known ingredient that can help with constipation.
It’s expensive, though, and the texture is quite watery. This is a good thing in the long run, but it might put off some cats.
- Low in fibre and carbs
- High-quality ingredients and high protein
- Moderate amount of fat
- High moisture content
- One recipe has pumpkin
- Expensive
- Watery
4. Royal Canin Wet Kitten Food — Best for Kittens
| Main ingredients: | Water, pork by-products, chicken by-products |
| Protein content: | 11% |
| Fat content: | 3% |
| Calories: | 76 kcal/can |
Royal Canin’s Loaf in Sauce Wet Kitten Food is a top-notch food for kittens 1 year old and younger. Kittens aren’t as likely to experience constipation as adult cats, but they are prone to digestive issues in general. It contains all the necessary nutrients for a growing kitten and will meet their high energy demands. The high-quality protein, as well as prebiotics and fibre, promote healthy digestion and antioxidants for immune system support.
Unfortunately, it’s expensive, and if your kitten proves to be picky, they might not want to eat this food.
- Good for kittens up to 1 year
- Contains the right nutrients for a growing kitten
- Prebiotics, proteins, and fibre for healthy digestion
- Antioxidants for the immune system
- Expensive
- Picky kittens might not like it
5. Royal Canin Feline Care Nutrition Hairball Care
| Main ingredients: | Chicken meal, corn, brewers rice |
| Protein content: | 32% |
| Fat content: | 13% |
| Calories: | 338 kcal/cup |
Royal Canin’s Feline Care Nutrition Hairball Care is a cat food that might seem odd to recommend hairball food for a cat with a constipation problem. But most hairball recipes include ingredients that aid digestion health and tend to be high in fibre. This one contains fibres, psyllium, and anchovy oil, which helps lubricate the digestive system. Many of the ingredients are also easily digested, and there are omega-3 fatty acids, which all work together for a much healthier digestive system. The fact that it helps with hairballs is an additional advantage because those can sometimes lead to digestion issues.
However, this food is quite expensive, and it’s dry food, which isn’t ideal to give to a cat with constipation issues.
- High in fibre
- Includes anchovy oil and psyllium
- Easily digested ingredients
- Omega-3 aids healthy digestion
- Manages hairballs, which can lead to digestion issues
- Expensive
- Dry food isn’t the best for constipation

| Protein content: | 11% |
| Fat content: | 1.8% |
| Calories: | 60 kcal/can |
Tiki Cat Food Aloha Variety has four recipes that have tuna as the main ingredient, followed by a different seafood for each, namely, shrimp, ocean whitefish, calamari, and tilapia. Pumpkin is commonly used for constipation and is the fourth ingredient in all four recipes. These foods are made with high-quality protein, which also makes them highly digestible and have high water content.
A downside is that the consistency can be watery, and some cats might not appreciate this.
- Four different recipes with whole tuna as the main ingredient
- Pumpkin is the fourth ingredient in all recipes
- High-quality protein makes it highly digestible
- High moisture content
- Sometimes, the consistency is too watery
- Picky cats might not like it
7. Blue Buffalo Sensitive Stomach Natural Adult Dry Cat Food
| Main ingredients: | Deboned chicken, chicken meal, brown rice |
| Protein content: | 32% |
| Fat content: | 16% |
| Calories: | 422 kcal/cup |
If your cat has a sensitive stomach, Blue Buffalo Sensitive Stomach Dry Cat Food might work for you. It includes a sugar prebiotic, which is derived from plants and increases the probiotics and healthy bacteria in your cat’s intestines, which can vastly improve digestion. It also contains flaxseed and barley, which are natural fibres that aid the digestive system. It has no artificial ingredients and has an excellent source of antioxidants.
However, it might make some cats experience stomach upset, and some picky cats don’t seem to like it.
- Contains a natural probiotic for digestion health
- Flaxseed and barley for natural sources of fibre
- No artificial ingredients or fillers

| Main ingredients: | Water, chicken, turkey giblets |
| Protein content: | 7% |
| Fat content: | 3.5% |
| Calories: | 84 kcal/can |
Hill’s Science Diet Urinary & Hairball Control Adult Cat Canned Food is designed to promote a healthy urinary tract, but it also has high fibre for hairball issues. It’s made with natural ingredients, which include natural sources of fibre that can aid in the health of your cat’s digestive system and dealing with hairballs. Omega-3 and -6 and vitamin E are included for healthy coat and skin. Added magnesium helps support the entire urinary system.

The ingredients are easy to digest, are nutritionally balanced and delicious, and help support heart health. The added antioxidants help with immune system support.
Unfortunately, this is an expensive cat food that some picky cats won’t always enjoy. Also, the size of the kibble is a bit large, and some cats might have trouble eating it.
- Natural fibre and high-quality ingredients for healthy digestion
- Easy to digest
- Supports heart health
- Antioxidants for immune system support
- Expensive
- Picky cats
- Kibble size is large
Buyer’s Guide: How to Find the Best Cat Food for Constipation
This buyer’s guide goes over what you should look for in cat food to help with constipation.
Treat the Cause
The diet that you put your cat on will depend on what might be causing the constipation. This means a visit to your vet so you can determine the underlying cause and the best way to treat it. If your cat doesn’t drink enough, you’ll need to take steps to increase their water intake. If your cat is overweight, you’ll need to invest in food that will support weight loss and address the constipation.
More Water
Cats tend not to drink as much water as they need, which can lead to constipation. This is why canned or wet food tends to be the most recommended food for a constipated kitty, as wet food is typically about 70% water. If your cat only eats dry food, try adding water to it. Also, consider investing in a cat fountain. Cats tend to prefer running water over standing water — this switch alone could increase your cat’s water consumption.
Fibre
This is a tricky one. For the most part, a high-fibre diet can help many cats with constipation, but too much fibre can have the opposite effect.
Insoluble fibres, which include cellulose, oat fibre, and wheat bran, help feces move quickly through the intestinal tract. This works for cats that don’t have GI motility problems.
Soluble fibres, which are found in oat bran, pectins, and guar gum, feed the cells in the colon, which aids and improves GI tract motility issues. Mixed fibres, such as beet pulp, psyllium, and pumpkin, have the benefits of both soluble and insoluble fibres.
So, look for cat food that states that it’s meant for weight management, indoor cats, or hairball control. These kinds of foods are typically high in fibre, but if your cat is already underweight or normal in weight, make sure the food has the right calorie count.
Keep in mind, however, that if your cat has megacolon, you should aim for a low-fibre and highly digestible diet. High fibre and megacolon do not do well together.
How much and what kind of fibre your cat needs should be determined by your vet. But you can start by adding a small amount of fibre to your cat’s diet and slowly increase the amount until you start to see positive results.
If you need to speak with a vet but can't get to one, head over to PangoVet. It's an online service where you can talk to a vet online and get the advice you need for your pet — all at an affordable price!
Weight Loss
Obesity can also increase the risk of constipation. This is where a diet that’s high in fiber can help some cats lose weight, and there’s the added benefit of increasing the motility of the intestinal tract.
Conversely, other cats will do well on a low-fiber, low-carbohydrate, and high-protein diet, which more closely resembles your cat’s natural diet. You can also encourage more exercise for your cat through play and cat trees. Speak to your vet for advice on the best ways to help your cat lose weight.
Digestible Diets
When shopping for cat food, look for words like “highly digestible.” This can help with GI motility and might help reduce inflammation in the intestines and decrease the amount of stool produced.
Check the Label
Other than looking for food that is for indoor cats, weight, and hairballs, you should look for food that is labeled for sensitive stomachs (usually combined with skin) and is a low residue, gentle, or meant for digestive and gastrointestinal issues. Speak to your vet so you know what kind of food is right for your cat.
