LOL! Proves my point, doesnt it? I only have one cat now but he sheds like crazy. Removing pet fur off furniture is not easy, but I have found cheap way to get a lot of it. I buy foam sponges at Dollar Tree - 8 for $1 - they are made for washing dishes. I run the sponge side over the furniture, and it removes a LOT of the fur. I used to buy lint rollers for this, but they are expensive and dont do any better of a job.
Let me tell you - some humans shed just as bad. There is one home I clean bi-monthly, and the woman has long hair. That LED headlight on my Shark always shows piles of long hair in the bathroom. And long hair can so easily clog a vacuum cleaner. I now stock a pocket knife in my work bag, just to get the hair out of the brush roll! NOT one of my favorite parts of cleaning!
