I attempted to resurrect it via battery this afternoon. It worked, sort of.
I'm going to tinker with it a little more, to see if I can get it to work. There's a little metal piece that I'm thinking was supposed to be glued to the battery cover that is now unglued. It's supposed to come into contact with the batteries and I have to be really careful with it. I'm not sure what I can do about the sound issue, or the pixel thing. Maybe there's a short in a wire somewhere.
Well, I go to a college that specializes in engineering. Perhaps I can find an electrical or computer engineering student who would know how to fix something like this. If I can get it fixed, I think it would be an interesting pet. It's a pity that the poor kitty had been sitting around for so many years and nobody got to enjoy it. I will keep you updated if I get the thing to work. Poor kitty. (Does anybody know how to fix these things?)
Here is a picture of the "Tee-Tee Kitty" if you're interested. It's actually a good picture.
