I don't know what to do about this. I feel like really, I need to train my cat. Atticus was sitting on the couch with me, and then Hamilton jumped up on the couch to chew on his cup (he loves plastic cups - he is closely monitored when he's doing this) and was completely not bothering Atticus, and Atticus got all mad at him. I had the camera next to me so I recorded it in hopes I could get some suggestions. Hamilton tries to get his cup, which rolled towards Atticus, and Atticus starts hitting him (note: while Atticus has claws, he's just hitting. He hasn't ever clawed Hamilton, or the other cats, or us - he just swats. He hasn't ever hurt anyone). In the end, Hamilton just gets the heck off the couch, which was the best answer - but is there anything else I could be doing here? I don't want to kick the dog off the couch when he isn't doing anything wrong. I don't want to kick the cat off the couch and make him feel like the dog takes priority. Should I just continue letting them work it out?
