We just bought Wally a feather teaser last night and gave it to him for an early Christmas. He was loving it! Chasing that thing all over the place, jumping it, pouncing it like nobody's business! Well, within a couple hours, I was petting him, and he playfully attacked my arm, this is the first time he's done that (he's only been with us about 10 days now). Grabbing on with both front paws and biting. He's only a few months old, so it's not that painful, but obviously we want to stop this behavior now. He then did it to my husband later, then my daughter. I'm not liking that, playful or not. I started thinking about it after he did it to my daughter again this morning, and I'm wondering if that teaser got him all hyped up and thinking it was ok to do that to our arms? Any advice?
