My pet rat (Captain Jack) is proud of emptying his litter tray when I've cleaned it. What cute things has your pets done?

Today is my cake day so I thought I would post a topic in here for the first time.

I have had Captain Jack since the start of October and he can be very mischievous. He also knows that if he sulks he will get fussing and attention.

He is always very proud of the fact that he empties his litter tray out that he will even squeak repeatedly to get my attention.
