got rid of cat hairs
We put sheets on the couch and that eliminated the cat hairs on the couch. Of course then we had sheets loaded with cat hairs. Neither washing the sheets nor putting them in the dryer dry got rid of the hairs.
This time I put Arm and Hammer Fabric Softener Sheets (guess any manufacturer's sheets would work) in the dryer with the dry sheets. I love it, the sheets are almost hairless.
