Quick Answer
Cats can eat gluten-free food, but they do not require it. Cats do not have issues digesting gluten like some humans do. However, some cat food brands offer grain-free and gluten-free options that may provide other benefits for cats.
Can Cats Eat Gluten?
Yes, cats can safely eat gluten. Gluten is a protein found in grains like wheat, barley and rye. Cats do not have issues properly digesting gluten like some humans with conditions like celiac disease. There is no evidence that gluten is harmful to cats when consumed in normal amounts from cat food or treats.
Do Cats Have Issues Digesting Gluten?
Cats do not have any issues digesting gluten like some humans do. Cats do not suffer from celiac disease or non-celiac gluten sensitivity. Their digestive systems can properly break down and absorb nutrients from gluten without any negative effects.
Some vets caution against feeding cats large amounts of gluten for other reasons, like the potential to trigger food allergies. But in normal quantities, gluten does not cause digestive issues for cats.
Can Cats Have Celiac Disease?
No, cats cannot have celiac disease. Celiac disease is an autoimmune disorder triggered by gluten consumption in humans. The immune system attacks the small intestine, leading to damage that prevents proper nutrient absorption.
Cats lack the physiological mechanism that causes celiac disease in humans. Consuming gluten does not trigger an autoimmune response or intestinal damage in cats. There are no reported cases of gluten triggering an immune or inflammatory reaction in cats.
Do Cats Need Gluten-Free Food?
Cats do not need gluten-free food. Since cats do not have issues digesting gluten or experience negative effects from eating it, there is no medical need to feed cats gluten-free food.
Many cat foods contain gluten from grain sources like wheat, barley and rye. This gluten poses no health risks to cats without underlying food sensitivities or allergies.
When Might a Gluten-Free Diet Benefit Cats?
In some cases, feeding cats gluten-free food may provide benefits:
- Cats with wheat or grain allergies may do better on gluten-free food.
- Some cats seem to digest grain-free and gluten-free food more easily.
- Gluten-free cat food often has higher protein and moisture content.
- Avoiding grains may help manage conditions like diabetes and urinary issues in some cats.
So while not required, some cats may benefit from gluten-free food for other reasons beyond gluten digestion itself.
Signs a Gluten-Free Diet May Help
Some signs that avoiding gluten by feeding grain-free or gluten-free food may benefit an individual cat include:
- Digestive issues like vomiting, diarrhea, constipation or gas
- Skin problems like itchiness, rashes or excessive shedding
- Ear infections
- Behavior changes like increased lethargy or irritability
- Changes in appetite or thirst
If a cat exhibits these signs on a diet containing gluten, it may indicate an underlying grain or wheat allergy rather than a problem with the gluten itself. Switching to a gluten-free diet could help resolve these issues.
Are Gluten-Free Cat Foods Healthier?
Gluten-free cat foods are not necessarily healthier overall than foods containing gluten. However, some gluten-free formulas may have characteristics that benefit cat health and nutrition:
Higher Protein Content
Many gluten-free cat foods have increased protein levels compared to grain-inclusive formulas. Cats thrive on high-protein diets, so this can be beneficial.
For example:
| Food Type | Protein Content |
|---|---|
| Gluten-free grain-free (Wellness CORE) | 44% minimum |
| Grain-inclusive (Iams ProActive Health) | 33% minimum |
The gluten-free formula has a minimum of 11% more protein than the grain-inclusive food.
Lower Carbohydrates
Gluten-free foods often have fewer carbohydrates, which may help cats stay fuller between meals. Lower carb diets can also benefit cats with diabetes.
Increased Moisture
Grain-free and gluten-free canned foods tend to have higher moisture levels since they lack dry carbohydrate-rich grains. This added moisture can help with hydration and urinary tract health.
Avoidance of Allergens
In addition to gluten itself, gluten-free foods avoid other common cat allergens like corn, soy and wheat. This elimination diet approach may help identify and manage food allergies.
Digestibility
Some cats seem to digest meat-based gluten-free foods more easily than grain-heavy formulas. This improved digestibility allows their body to absorb and utilize more nutrients.
So while not always better across the board, some characteristics of gluten-free cat foods may provide benefits for certain cats.
Risks of Gluten-Free Cat Food
There are not many risks directly associated with feeding cats gluten-free food. However, there are some considerations:
- Reduced fiber – Heavily meat-based gluten-free foods may be lower in fiber, which helps digestive and bowel health.
- Lower taurine – Taurine is an essential amino acid for cats found in meat. Gluten-free vegetarian formulas may be deficient.
- Incomplete nutrition – Poorly formulated gluten-free foods may not provide balanced and complete nutrition for cats.
- Price – Specialty gluten-free and grain-free foods often cost more than traditional cat food.
- Palatability – Some cats dislike the taste, texture and smell of unfamiliar gluten-free foods.
To avoid these risks, choose reputable gluten-free cat food brands and transition diets slowly by mixing old and new foods. Consult your vet on appropriate gluten-free options for your cat.
What to Look for in Gluten-Free Cat Food
When choosing a gluten-free cat food, look for these signs it provides balanced and complete nutrition:
- An AAFCO nutritional adequacy statement for the life stage of your cat (maintenance, growth, pregnancy, etc.). This signals the food meets your cat’s nutrient needs.
- High quality animal- or fish-based proteins as the first few ingredients.
- Moderate fat and calorie levels to maintain an ideal weight.
- Added vitamins, minerals and fatty acids like taurine, vitamin E and omega-3s.
- Decent fiber levels around 2-4% to support healthy digestion.
- A moisture content of at least 75% for canned foods or 10% for dry foods.
Avoid gluten-free foods with high carb fillers like potatoes or peas instead of quality meat ingredients. Reading reviews can also help assess factors like a food’s palatability and potential for gastrointestinal upset.
Examples of High Quality Gluten-Free Cat Foods
Some well-formulated, nutritionally balanced gluten-free cat food options include:
- Wellness CORE Grain-Free Pate
- Nature’s Variety Instinct Grain-Free
- Merrick Grain-Free Limited Ingredient Diet
- Blue Buffalo Wilderness Grain-Free
- Holistic Select Grain Free
These all deliver complete nutrition in a grain and gluten-free formula. There are many other reputable gluten-free brands available for cats with different health needs and preferences.
Transitioning to a Gluten-Free Diet
When switching your cat to a gluten-free food, go slowly to allow their digestive system to adjust and prevent gastrointestinal upset:
Step 1: Choose the new food
Select your new gluten-free brand and recipe based on your cat’s needs, preferences and health goals. Get your vet’s input on an appropriate option if needed.
Step 2: Transition over 5-7 days
Over a period of 5-7 days, gradually increase the percentage of new food and decrease old food. Aim to reach a ratio of 25% new food and 75% old food by Day 3.
Step 3: Feed 100% new food
After 5-7 days of slowly adjusting the ratio, your cat should be ready for the new gluten-free food exclusively. Monitor their condition for signs of any digestive upset.
Step 4: Provide extra hydration
Ensure your cat has plenty of clean, fresh water as their system adapts to the new food over the next 2-4 weeks. Add moisture by feeding wet food or mix water into dry food.
Step 5: Consult your vet if needed
If your cat shows signs of digestive distress like vomiting, diarrhea, constipation or lethargy, discontinue the food and seek veterinary advice. Your vet can recommend adjustments or alternatives.
With proper precautions, most cats can successfully transition to a nutritionally balanced gluten-free diet. Take things slowly and monitor their condition closely.

Common Questions
Are grain-free and gluten-free the same for cats?
Grain-free and gluten-free are similar but not identical. Gluten-free means avoiding gluten, a protein found in some grains like wheat. Grain-free means not using any grain ingredients like corn, wheat, rice or oats. So grain-free foods are typically gluten-free as well since they avoid gluten-containing grains.
Can cats eat gluten-free bread?
Small pieces of plain gluten-free bread should be safe for cats to eat as an occasional treat. Avoid bread with unhealthy additives like sugar, honey or raisins. Introduce new foods slowly to watch for signs of digestive upset or allergies.
Do grain-free cat foods cause heart disease?
Some early research raised this concern due to unusual levels of taurine deficiency in cats eating certain grain-free diets. However, this is likely caused by diet formulation issues rather than a direct effect of avoiding grains. Well-balanced grain-free and gluten-free foods that contain sufficient taurine are not known to increase heart disease risk.
Conclusion
Cats do not require gluten-free food, but some cats may benefit from grain-free or gluten-free diets. These formulas often have higher protein, fewer carbs and increased digestibility. Avoiding grains may help manage certain health conditions. When choosing gluten-free cat food, ensure complete nutrition with quality ingredients. Slowly transition cats to prevent digestive upset. With the right food and precautions, feeding your cat a gluten-free diet is safe and may offer advantages for some individuals. Discuss options with your vet to see if a gluten-free food makes sense for your feline friend.
