he want to play with you! the towel have your smell. also, he chase after your trousers because he want you to play with him.
however, you should ignore him when he do so. it's because if he bite your trousers and you have big reaction, he will conditioned this bite with your big reaction (he see your reaction (shouting, running, ....etc.as "play with him"). This means you are encouraging him to bite your trousers. Also, if you do so you will allow him to decide what time to play with you, not you. this will weaken your position as the "master of the house". he will think he is the master.
this does not mean that you do not play with him at all. you should spend more time with him and play with him more to build your relationship. however, it is YOU to decide what time to play with him, and what kind of games with him.
