This is a very common discussion on this board, as well as many others, a lot have taken it upon themselves to learn more about nutrition, ingredients and whats really involved in all of it, it's wonderful to find such determind and concerned pet owners on this forum.
I'm also glad to see that you share similar educated views in reguards to many aspects of feline nutrition.
I have been to busy with work to come here much anymore, it's good to see yet another member wanting to help out, welcome to the board!
Queen Of The Nile:
I don't know if you have checked out the Waltham foods or not, but here is the ingredients for dry and wet incase you have not, so you can make a comparison. Generally if a perscribed diet is working it's a good idea to keep them on it, until you and your vet come up with another plan for your cats life long nutrition. There are other diets which can work that are non perscription, but perhaps you should wait on that until your cat reaches and maintains his optimal weight.
Have you voiced this concern with your vet before?
