HELP! I have a sweet cat who due to the fact that his teeth were rotting out (and are now all gone) had to be switched over to wet cat food a few years ago. I tried a couple feeders (Cat Mate C20 and Paw Wise Feeder), and both have not lasted a year before my smart but awnry kitty has learned how to break them open. I need a feeder for when I go out of town so the cat sitter only has to come over once per day. I'm getting desperate. My next move may be to put double-sided sticky tape on this feeder, but I was wondering if anyone had recommendations on wet cat food feeders that are sturdier and that a determined cat won't break into? If I can't figure this out, I'm going to have to board him every time I leave town, which will get expensive and he certainly won't be happy. HELP!
