A store full of cat paraphernalia... I'd go crazy in there. I've got a collection of metal cat miniatures and would probably see things I'd want to add to it.
It's nicer to have two real live cats inside the house than a big inflatable one on top of it. Trust me on this one. And you can't have both, because your real cats will find a way to bite your inflatable cat and then you'll have to get a rubber patch kit and it won't work right because there'll be a slow leak so it'll just look like there's a floppy kind of cat puddle on your house, which is almost as bad as having one of those chintzy inflatable Santas.
Yep! For a long time, my bed was an air-bed with a collapsable frame. (The logic being not to weigh myself down with heavy furniture until I'm in the type of house I want, but then the economy went other than I had hoped, but anyway...) Needless to say, the air mattresses didn't last long, always needing patching or replacement. I went through three air mattresses. (Cats want to be piled around their owners when the owner is asleep. Claws and air mattresses just don't mix.) I finally ended up using last year's tax return to buy a real bed, so as to finally get a decent night's sleep and avoid back problems.
Now my kitties amuse themselves by destroying the mini-blinds (replaced them three times already) and the carpet. If I don't want the replacement blinds destroyed, I have to keep applying "Fooey" spray to them.
