My M-i-L's cat Spook does that. Her tree is fake (allergies), but it's a nice one, so I guess she (the cat) had good claw-holds in there. Sometimes we'd walk down the hallway and see an extra set of "lights" on the tree. We made sure to ignore her, because she's very skittish, and she was always very careful going up and down, but if you startled her, all bets were off. :P Ornaments, tree 'branches' and who knows what else would go flying. heh.
She's a very playful cat, as long as she doesn't think you'll move toward her while you're playing.
She and Rainey are great playmates. :p They chase each other through the house, at a gallop. Apparently from downstairs, it sounds like a herd of elephants. heheh.
I was trying to take a good picture of this
when Rainey decided she liked it too.
As I'm sure you all know, it's hard to catch critters in action (especially with a bad camera). So, these are fuzzy, but I think you can see what's goin' on! :P I never did get a clear picture of that thing. XD
I have a lot of pictures, but I don't have a lot of time right now, so I'll leave you with one more:
Or, well, two.
This little guy showed up in my parents' garage a couple of years ago. Ginger was not pleased! (I know people joke and say that Canadians have pet beavers, but I'd never seen one before. haha. We're not even sure how it managed to get in, since Ginger's pretty watchful. o.o)
Anywho, off to finish packing!
