I did not notice in the item description that these pads do not have a removable cover and they have a fiber that holds the hair.  I put them into a pillow case, so I won't have to sit and pull hair out of the fibers, and I can also wash the covers.  My cats like them.

Pros: Cats love them.
Cons: Fibers hold the hair - they should come with a cover, or at least the option to buy one.
