It was pretty funny (after the fright!) when Noelle fell into the toilet as a kitten. The look on her little face was priceless... Since then, she's learned how to balance on the seat, if for some reason I forget to put the "lid" down.
She's also quite the climber... In my previous apartment, she loved climbing up the side of the doorway, and then get on top of the door if she could manage it. Sometimes she'd just get stuck half way up, and I had to go an rescue her, if I could stop laughing!
Vinka sometimes seems to get stuck. Since she's so big, she doesn't like jumping or climbing until she's had plenty of chances to make sure it's a safe place. Thus, she gets stuck in places, with her front paws on a table, say, and her back legs still on the couch. It's seems that she can't just step over, but once she's started to do that, it's almost impossible to jump the rest of the way.
Pretty soon after I got my new bed, sort of a sleeping loft thingy, the bed's on poles of about 5 feet, with my desk underneath Vinka got stuck again. Vinka was as usual walking on the desk while I was doing some work, and suddenly she reached up and grabbed the big 2 by 4 that runs along the middle of the bottom of my bed. She grabbed it, and... Was left hanging! The desk is not directly underneath that 2 by 4, so she couldn't get down, her back feet weren't touching the desk anymore. She was just swinging there, holding on with her front paws... It was hilarious!
I did help her down, of course. Hasn't done that since.
