I have never seen a kitten able to get so completely engrossed in playing.

This morning we were headed to a pickup, and Harri was in the overhead
playing with stuff. She decided that one of my towels was being
especially bad and needed to be disciplined, so she grabbed it with both
front paws and bunny-kicked furiously with her back paws.

When I heard this I glanced up to see what she was doing. Besides seeing
what she was doing I noticed that she had her back to me, and that she
was right up against the cargo netting and was pulling it down a bit. I
told her "better not roll over or you'll fall out." As soon as I said
that she rolled over and fell out of the overhead.

Since I saw it coming I was able to just stick my right hand up behind
her and catch her as she rolled over. I then just deposited the entire
bundle of kitten and towel in my lap. A few seconds after I put her in
my lap she looked up, did a double take, and startled. The expression on
her face was something like "Whoa, dude, how'd you do that? I was in
that overhead thing..."  She had no idea whatsoever that she had fallen
out, she was so totally engrossed in killing that naughty towel.

She then jumped off my lap and into the sleeper. She seems to still be a
little incensed that I teleported her out of the overhead - that must be
what happened, because she sure doesn't remember leaving the overhead by
choice!
