As plant-based diets become more popular among humans, many pet owners wonder if the same approach can be taken with their feline companions. The question of whether cat food vegetarian options are safe or beneficial is more than just a lifestyle choice—it touches on biology, ethics, and feline health.
In this article, we’ll take a deep dive into vegetarian cat food, including whether it’s suitable for obligate carnivores like cats, the pros and cons, available commercial options, and how to make an informed transition. If you’re already exploring alternative diets for your feline, check out our article on vegan wet cat food as well.
Are Cats Naturally Vegetarian?
Cats are obligate carnivores, which means their bodies are biologically designed to consume and digest animal protein. Unlike dogs, who are omnivores, cats need specific nutrients found in animal tissues, such as:
- Taurine – An amino acid essential for heart and eye health
- Arachidonic acid – A fatty acid only found in animal fats
- Vitamin A – Cats cannot convert beta-carotene into Vitamin A as humans do
- Vitamin B12 – Derived primarily from animal products
So can a vegetarian cat food diet work? With careful formulation and supplementation, yes—but it requires vigilance and veterinary guidance. We explore these concerns more deeply in our piece on plant-based cat food.
What is Vegetarian Cat Food?
Vegetarian cat food typically excludes meat, poultry, and fish but may include animal-derived products like dairy or eggs. Vegan cat food, by contrast, excludes all animal-derived ingredients. These diets often use plant-based proteins such as:
- Pea protein
- Chickpeas
- Lentils
- Brown rice
- Quinoa
To meet nutritional needs, synthetic versions of taurine, vitamin A, and other nutrients are added. This makes commercial vegetarian cat food highly engineered to meet AAFCO standards.
Why Choose a Vegetarian Diet for Cats?
Pet owners opt for vegetarian cat food for various reasons:
- Ethical beliefs: Vegans or vegetarians may want to align their pets’ diets with their own
- Environmental concerns: Reducing meat consumption can lessen environmental impact
- Food allergies: Some cats are allergic to common proteins like chicken or beef
- Curiosity or trial: Some owners experiment to see if their cats thrive on non-traditional diets
While ethics and sustainability are noble motivators, the cat’s health must remain the top priority. For a deeper dive into ingredient consciousness, visit our guide on vegan canned cat food.
Risks and Concerns with Vegetarian Cat Food
Feeding a vegetarian diet to a carnivorous animal carries inherent risks. Without strict formulation, cats could suffer from:
- Heart disease (dilated cardiomyopathy) due to taurine deficiency
- Blindness from vitamin A deficiency
- Poor coat quality
- Muscle wasting from low protein digestibility
Always consult a veterinarian before switching your cat to a vegetarian diet, and get regular blood work done to monitor nutrient levels.
Best Vegetarian Cat Food Brands
Some brands have formulated vegetarian or vegan cat foods that meet nutritional requirements. Here are a few you can explore:
1. Ami Cat
Ami Cat is an Italian brand offering a complete vegan dry food made with vegetable proteins and fortified with essential nutrients. It’s widely used in Europe and gaining popularity elsewhere.
2. Evolution Diet
This brand offers both wet and dry formulas and has been producing plant-based pet foods since the 1980s. It’s fortified to meet feline dietary needs.
3. Benevo
UK-based Benevo produces a vegetarian and vegan cat food that is AAFCO-compliant. Their formulations include taurine, arachidonic acid, and vitamin A.
4. Wysong Vegan
Wysong offers a vegan formula intended for intermittent feeding. They recommend mixing it with their meat-based foods for best results.
How to Transition Your Cat to a Vegetarian Diet
Switching to vegetarian cat food should be done slowly and thoughtfully. Here’s a suggested plan:
- Mix 25% vegetarian food with 75% of their usual diet for 3-5 days
- Gradually increase the vegetarian portion over 2–3 weeks
- Watch for signs of intolerance (vomiting, diarrhea, lethargy)
- Maintain hydration—some vegetarian diets may be drier
- Visit your vet for regular checkups and nutritional blood panels
Signs That Your Cat Is Thriving on a Vegetarian Diet
If your cat is doing well on a vegetarian or plant-based diet, you should observe the following:
- Stable weight and energy levels
- Shiny coat and healthy skin
- Regular, solid bowel movements
- No signs of nutritional deficiencies
If your cat shows negative symptoms, revert to a meat-based diet and consult your vet immediately. A transitional product like vegetarian wet cat food can be gentler on digestion while testing new ingredients.
Homemade vs. Commercial Vegetarian Cat Food
While some pet owners prefer to make their own cat food, vegetarian diets are especially tricky to balance at home. It’s safer to stick to commercially formulated products unless you’re working with a certified veterinary nutritionist. Common homemade ingredients include:
- Cooked lentils and peas
- Quinoa and brown rice
- Carrots and pumpkin (for fiber)
- Supplemental taurine and vitamin B12
However, even the best-intentioned homemade diets can fall short, so proceed with caution.
Ethical Considerations
For many vegetarians and vegans, feeding meat to pets creates a moral dilemma. While empathy is important, so is respecting your pet’s biology. Feeding cats a vegetarian diet for ethical reasons is a personal choice that must be carefully weighed against scientific evidence and your cat’s health.
Explore ethical alternatives, such as products using lab-grown meat or insect protein, which are emerging in the market and may offer a compromise.
Conclusion: Is Vegetarian Cat Food the Right Choice?
Cat food vegetarian options are not inherently harmful—if properly formulated and monitored. While it goes against a cat’s natural dietary design, modern nutrition science has made plant-based feline diets possible in some cases.
If you decide to go this route, choose a reputable brand, monitor your cat’s health closely, and stay in touch with your veterinarian. For more plant-based options, read our latest on vegan wet cat food and vegan canned cat food.
