I have two cats that I have had for about a year. I have left the cats alone in the house every weekday when I went to work with no problems. A few weeks ago, one of my cats apparently discovered the trash can in the kitchen (it has always been there) and ever since he is almost constantly standing on his hind legs trying to get into the trash and tearing at the bag. Several times already he has knocked the entire trash can over spilling garbage all over the floor while I am gone and he has even done it twice while I was out of the area for a few minutes taking a shower (most recently this morning). No matter what I do I cannot get him to stop. It is extremely frustrating because I now cannot even leave the kitchen without carrying the garbage can across the house and locking it in the bathroom where the cats cannot get at it. (I have two cats but Hobbes is the one who is overly curious and always picking at the garbage.) I have read that the proper way to discipline cats is to ignore them but I obviously can't ignore them spilling trash all over the floor. What can I do to get them to stop this? I can't always be locking either the cats or the garbage can away every time I leave the house or take a shower.
