Pebbles is 13 weeks now, at first he was so affectionate and loving, he loved to sit next to me being stroked and cuddled. Now everytime I walk past him he waves he paws at me and then jumps at my leg and wraps his teeth around my ankle, lol! He does it to the kids too. Everytime I go to pick him up he quickly turns around and wants to bite me. My hubby says it is him being playful but I don't like it. I never get to just sit with him now and have some cuddles Is it normal?
