We moved into our first place a few weeks ago, and it's an older home that needs some work. We feel pretty good about what needs to be done, but one thing in particular that I'm concerned about is that there's strong evidence of previous cat in this home. It wouldn't be a problem if my mother weren't highly allergic to cats. This might work well for my husband though. ;) When we first moved in she spent 30 minutes in the home and couldn't breathe when she left, and at that point I hadn't connected the dots that cats actually were here, but now that I have, we need to remove all cat dander/hair. I've found matted cat hair in the coils of the refrigerator, and that got me thinking... where else am I not looking that I should be? I'd like to not get too crazy unless it's required. Any ideas?
