So Major Drills is constantly asking me to play with my pets, but I can't because everytime they tell me it was boring. They are too happy, haha! I've taken away the minions from two of them but it hasn't helped, even after a few hours!

Are your pets in the resort maybe? if so that could be the problem. If not just wait a day, then they should be unhappier so you can play with them.

they're not in the resort... ok I was probably just not patient enough. I thought, since they get hungry so quick they'd get bored just as quickly. Thank you.

@ Nitrel As far as I know, waiting is probably the best option. Give it 24 hours, and it probably should be down. I heard that there are certain ways to decrease happiness during battle, but it is not easy. See this post for reference.
