Thanks for the feedback. I figured while the water probably wasn't ideal for them to drink, if it was horribly toxic, there'd be a lot more dead cats around Christmastime. Even so, I asked my husband to do something this morning to keep Kirin out of the water so that'll be a non-issue soon.

The tree is well anchored - the stand we have is very secure. Coupled with the fact that Kirin is maybe 5 lbs. and Sushi's only about 4 lbs., I don't think they'll be able to bring down the tree. Maybe next year. For now, they're just having fun trying to bat down the lowest ornaments.

Here is the tree, complete with Kirin underneath.
