In the past I have always fed my cats Science Diet, but then we got Hank and tried Purina and he preferred it over Iams so I thought the cats might also prefer Purina and gave it a try. Well they starved....Their bowl stayed empty and they begged the entire family for food so I discovered all food is not created equal. I think these guys are happy to have good food again.
On a side note: Pete chews into ALL bags. We have to hide his food and everything from him. He has chewed holes in his food bags, litter bags, treats, bacon bits, bags of candy, some scrapbook supplies I had. I've never had a cat like this but this is Pete's thing, his one and only fault. This time I caught him on camera!
