answer:Three month old kittens are like toddlers. They’re going to run, play and fumble. Make sure he knows it’s not acceptable to be aggressive towards you, and that he respects your rules about curtains/furniture etc. He’ll calm down a little bit after he’s neutered- but time will be the biggest calming factor. If you put aside about half an hour daily to really play with him, it can help him get out some of that energy. Wand toys, tossing toys or a laser pointer are all good playthings- just be interactive with him to keep him interested.
