We have had Dilbert for a few weeks now. We slowly introduced him to the dogs and he was unsure at first but now he seems comfortable around them. Maybe too comfortable now. We have 3 dogs a lab, a lab/pit mix and a pug mix. The cat, Dilbert, will come up to the dogs, rub against them and then smack them in the face with his paws. He will then turn around rub again and then smack again. He only does it with the big dogs. I thought at first they were following him too much and he was trying to get them to go away but after watching for awhile I realize he will go to them to smack them. Is this playing or is he just being nasty? How do I get him to stop? Thanks in advance!
