Product review (5 stars): No more clogged utility sink
We have 2 long haired cats. Our washing machine drains into a utility sink and we had a filter in the drain to prevent the hair from getting in the plumbing. There is so much hair that the filter would clog and then the sink would over flow. No fun.

These little guys attached to the end of the hose and will last about 15 washes between changing (could be more or less for you). They trap most if not all of the cat hair (and other stuff) and we haven't have an over flow since.

Well worth the price imho.
