I have two siblings, boy and girl. They are 6 months old. We have a huge problem. As soon as both me and my husband walk off the kitchen our two cats jump on the kitchen table and counter tops and look for food to steal. Don't think that they are hungry. They do this even after they are fed. They didn't use to do that, but of course they were small and couldn't jump that high. Yesterday my huspand was helping me cook and he was cutting meat he turned away, our female put her paw on the table grabed the piece and ran away. They also figured out how to open the garbage door. So now they raid our garbage too. I started giving them more to eat but now I feel like I'm overfeeding them. When they walk away from their plates their stomack is huge like a baloon. How do I discipline them? Why do they do that?
