My 4 year old male kneads like no kitty I’ve had before. His hind legs quiver, arches his back and then he rubs his backside and genitalia on whatever he’s kneading.. not going to lie but it’s almost like he’s cat master-bating I noticed a few wet spots on the towel he was just doing it on. Perhaps marking it? I’m not so much worried there’s something wrong just curious if other people have experienced. I read some threads and he doesn’t exhibit any aggression like biting the object or anything. I took a video but I’m getting an error that it’s the wrong format ( iPhone) I can try again though. Thanks cat loving family
