Hahaha, brilliant.
What a smart little flash, this is! My, god! Well, I just loved the idea of this being about a 'cat' who loved to live and play but in the end, ended up just being hooked to the computer and living indoors all the time. This has a rather powerful meaning and that is just simply: Get the fuck off the computer, go outside and enjoy yourself!
Now, we know some people won't do that, but still, it's a nice try and a rather powerful moral. :P
I liked the fact that you were also experimenting with this flash instead of doing your old routines of using the brush tool. It's great to experiment with new and old things. The graphics were nice on the cat and on the computer (nice use of filter effects, by the way!) but I did feel that the children outside should of had a bit more work done to them and even the football. I also felt like the children should of been kittens, as well.
Although, there was a bit that I was picky with with this animation, I still really liked it and I'm going to add it to my favourites. Nice short with a good choice of music, too.
8/10.
