OMG - sorry about that crazy lady. I kinda rolled my eyes when I read "don't throw anything at me" - and then I saw what that nut wrote - maybe it was just her idea of a joke. Are folks actually that mean to you? (I mean other than the crazy lady?) Next time someone gives you a hard time, just say "The Civil War is over, Y'ALL!" (And if they're REAL jerks, add "And the South lost!")
ANYWAY, I've got 4 cats and an allergic husband, too, so I know what a pain allergies can be. Keeping the cats out of the room you sleep in can help - but the allergens that are already there stick around for MONTHS.
But honestly, I think you're gonna be fighting a losing battle until you can figure out a way to get rid of that wall-to-wall carpet. Maybe you can try just one room at a time, and if you do it yourself, you can do it cheaply. (Especially if you count how much you spend on allergy medications, or fighting colds, or vacuuming. Or washing the cats!!! Good grief - I think I'd start living in a tent in the backyard before I washed all 4 cats every weekend. Talk about lowering your quality of life. And don't think the cats will be any happier about it, either!)
Now, I have just been re-doing my kitchen floor, which I have HATED for almost 10 years now, but I could never afford to replace it. Finally, I was at Home Depot or Lowes and I saw some great-looking peel-and-stick vinyl tile - for around $1.00 a square foot, and I decided I just couldn't take that floor anymore. (I mean, the seams had been coming apart and were held together with duct tape - and they'd had duct tape for 10 years! Every now and then, we'd spiff the place up and put down shiny new duct tape. :-\ )
Vinyl flooring really does look so much nicer these days,
not at all like the cheesy ones we had in the 70s. They even have ones that look like long wood planks, in oak, hickory, and one that I really liked looks like reclaimed wood.(I ended up going with a square tile that I swear looks exactly like travertine. Maybe it was $1.30 a sq. foot.)
OH! And IKEA has flooring these days, too! Good looking stuff, and of course, super super cheap. Gotta love IKEA!
One last tip, I have a friend who has allergies to pollen and plants and whenever he's on a trip, he stops by a grocery store and picks up some local honey. (I mean, I pick him up at the airport and he immediately makes me stop by the grocery store.) He says when he has a tablespoon or so of local honey, it helps his allergies. Sounds a little new-agey to me, personally, but he swears by it. This might work because it's a quick way to get acclimated to a new place - since you're living here and not just here on a trip, it may not work as well. And of course it won't help much with cats, but I figured a bit of honey can't hurt.
