I have a 17 year old cat, he is very agile and can get away from Yorkie but I don't like him chasing the cat,

how can I stop him doing that.
My husband says he doesn't do it while I am at work and he is at home looking after them, why does he do it for me?

I do punish him by putting him in the pen for a few hours, but this doesn't seem to be working, most of the time they are OK it is just when Yorkie gets a bit playful, and thinks the cat might like to play with him.
Looking forward to getting a remedy.
Thanks Leone
