I have a couple of questions about cat food. I have been feeding my 4 girls wellness wet grain free cat food for a while now but it has gotten to the point where we can't afford it anymore. I am in a dilemma as to whether to feed my cats all grain free dry food because it is so much cheaper or a cheap wet food? Any suggestions would greatly help. I really love my babies and wish I could afford to give them the best but I just caNt right now and I feel awful about it. I don't want to feed them something that will hurt them.
