Vegan nutrition is trending – but what can be a conscious decision for humans is simply not species-appropriate for dogs, and especially for cats. This article is not an attack on vegan people – but a clear, fact-based appeal for the welfare of animals.
The Dog – Carnivore with Omnivorous Traits
Dogs have evolved over millennia as human companions and can indeed utilize a wider range of foods than cats. Vegetables, potatoes, or rice can be beneficial in moderation – as a supplement, not a substitute.
But: a dog needs animal protein. Muscle meat, organs, bones – that's what its digestive system was made for. Soy, tofu, or other plant-based protein sources do provide protein, but not in the biologically available form that a dog truly needs.
Facts:
- Dogs require essential amino acids like L-carnitine and taurine – these occur naturally only in animal products.
- Plant-based protein has a significantly lower biological value for dogs.
- Vegan dog food almost always contains artificial additives to compensate for nutrient deficiencies.
The Cat – Obligate Carnivore, No Exceptions
For cats, the situation is even clearer: cats are obligate carnivores. This means their body is biologically unable to synthesize certain vital nutrients from plant sources.
What cats absolutely need from meat:
- Taurine – without taurine, heart problems and blindness are a threat.
- Arachidonic acid – a fatty acid that cats cannot produce themselves.
- Vitamin A (retinol) – cats cannot convert plant-based beta-carotene.
- Vitamin D3 – only usable from animal sources.
Feeding a cat a vegan diet is not a lifestyle choice – it is a danger to the animal.
What about commercial vegan prepared food?
The pet food industry has responded to the trend – and produced vegan dog and cat food. Why? Because there's a market. Not because it's good for the animals.
These products are usually packed with:
- Synthetic vitamins and minerals
- Artificial amino acids (e.g., synthetic taurine)
- Stabilizers, emulsifiers, and preservatives
The paradox: those who buy vegan food to live more naturally often feed their pet the most artificial food imaginable.
What do studies & science say?
The scientific data is clear:
- A study by the University of Winchester (2022) showed that dogs on a vegan diet can appear healthy – but long-term consequences and nutrient deficiencies were not sufficiently investigated.
- The European Pet Food Industry Federation (FEDIAF) emphasizes that cats, as obligate carnivores, are absolutely dependent on animal nutrients.
- Veterinarians regularly warn of taurine deficiency in vegan cat diets – with fatal consequences for the heart and eyes.
- The British Veterinary Association (BVA) explicitly advises never to feed cats a vegan diet.
Our Clear Opinion
Those who reject meat – for ethical, religious, or personal reasons – deserve respect. But including an animal that is biologically dependent on meat in this decision comes at the expense of the animal.
There are wonderful pets that are naturally vegan: rabbits, guinea pigs, chinchillas, many birds, turtles. Those who don't want meat in the house can find a loving companion there – without compromising animal welfare.
Dogs and cats are not among them.
