Vegemite loves to jump up and try to swat the little thingies that stop the door handle from banging on the wall (what are those things called? lol).
Also, a couple of years ago, Honey Boy took a small female personal item, pawed at it until it came out of it's wrapper and then walked around with it hanging by it's string from his teeth! I was so surprised, I chased him and he went under the bed with it and wouldn't come out. I had to leave him be, hoping he'd just leave it there. A few hours later, I looked under the bed - no thingie. I'm thinking, oh geez, my housemate has some of her family coming over! I have to find it! I just about had a hernia looking for it. In the end, I had to tell everyone who came into the house that I had a cat that stole things, so if they came across said thingie, I wasn't a dirty person, it was the cat!
I never found it.
