Feline nutrition is one of those areas which has been complicated by the market explosion of pet-foods, really only in the past 20 years. I am so pleased to hear that you are going to do further research, and are interested in getting Lily's. I sent the ingredients and analysis to a person in the US who is studying feline nutrition, feeds all her own cats (26 of them) a raw diet, and she said Lily's was excellent in her opinion. It works out at less than £1 per pouch, and I think it's fantastic value for money, compared to the absolutely scandalous contents of some of the brands. Bear in mind that many of these big companies have only commercial success in mind, and for that reason many of them have sponsorship agreements with vet colleges and clinics, so the vets agree to plug them, and even sell their products. It is scurrilous practice, and I am certain it gives some caring vets sleepless nights, but they have to go along with it if they work for a bigger practice, or need the backing. And of course, bottom line is that it is not in vets' interest to promote good feline nutrition, as the fall-out of that is less vet visits for our cats!! Good luck to you and Tosca in your search for the best diet. He has many hours of good chewing ahead (we're beginning to broach the whole BONES issue in this house - it's only MY fear we have to get over - the girls are dying for it!)
