Oh no, these replies are not very encouraging!!! Wah!!!
Great idea about gradually making his area bigger, thanks. I've thought about that, but the way our home is laid out makes it very hard to just give him one room, etc. Well, except for a bedroom or a bathroom, but that would really separate and isolate him... and I'm SURE he'd claw and scratch and ruin the doors!!!
I've thought about trying to gate off the kitchen, but there are 3 doorways, and the cats must go through the kitchen to get to the basement where their kitty litter is. It would just be very impractical and awkward at best.
I would really hate to have to send him to the post-a-note factory... (I told him he's probably too little, the glue factory wouldn't want him!) I keeed, I keeeed!!!
