The cats who we have cared for have eaten mashed tofu, garbanzo beans, seaweed, squash, some grains, seitan, etc. topped with nutritional yeast, oil, and a dash of salt (for flavor), and supplemented with nutrients designed for vegan cats (read below). This little feline also ate regular helpings of a dry kibble called ‘VeganPet‘, which is produced in Australia and available in New Zealand.
The website veganpet.co.nz has lots of information about the specific nutritional requirements of cats, and how to meet these requirements without the use of animal products. When we have taken care of cats, we have used feline supplements such as “Vege-cat”, as well as various fortified vegan cat food products.
Many vegan cat caregivers have reported greater success with changing the diet gradually, by introducing small amounts of vegan food into the animal-based meals, and increasing it a little at a time until the meals are fully vegan. This allows the cat’s digestive system to adjust, rather than going into shock, which can happen with too much plant-food all at once. There is a digestive enzyme marketed by Harbingers of a New Age that seems to be helpful, especially for the transitional period. The same company also markets other animal care products, including something called Vegecat phi™, which helps to prevent urinary tract infections.
