OK, this is kind of a weird but troubling situation. My mom won't buy anymore canned food for the cats and dog since they are making a mess with it. She also says that canned food is bad for their teeth. My cats and dog are so used to it, they won't eat the dry cat food. I keep insisting with my mom that we buy a few cans, but she won't. I am tempted to buy cans secretly, even if I will get in trouble. Could you give me some advice as to what to do?
