My male cat had just a little operation to remove a 'crystal' which blocked him from peeing. After that the vet nurse advised me to strictly cut any food apart from certain Virbac dry food brand which they sold me and by the way was 10x more expensive than usual cat food.
I asked her if it is OK to feed the cat with human grade poultry or fish, but she said no, only the 'tried and tested' brand.
I am not convinced that my cat is doomed to eat only that sort of food for the rest of his life. So I'm wondering what is the best diet for cats in this situation? Which foods are allowed and which are forbidden?
