So about 2 years ago I took in a cat from a person who didnt look after him. The cat never had food so he always ate what was laying around. I got him fixed right away. I started by feeding him whiskas and wet food. A year ago we moved and relatives had given him some human food wich i asked them not to do. Now he eats everything. I changed his food brand to blue buffalo to no avail. He knocks cookie bins off the counters, he rips open bread bags. If you accidently leave a bag anywhere empty or not he tears it everywhere. I dont have cub boards so I moved the items on the shelves, he managed to pull things off the shelf. I scare him off every time or chase him out of the kitchen. I dont know what to do anymore, its becoming a big problem. Any suggestions?
