I've been messing around with The Sims 3 on my PC, and I've got the Pets expansion pack. With that, I discovered that the customization options for keeping small animals are really pretty advanced. When I went to stock my Sim's Snake Tank, I discovered that I could choose between a Garter Snake, an Emerald Tree Boa, and a "Mini Python", which is basically a really bitty ball python. :D You can do a lot more interacting with your Minor Pets than you used to be able to, as well. For example, a screenshot of my Sim holding Magnus the Mini Python.

Anyone else have fun (forum-appropriate) screenshots of their Sims they want to share?
