This is exactly what I do too. Since I have 4 cats, it sure saves me money.

Please don't use "Bio-Spot". Here's some information about how bad it is:http://www.elversonpuzzle.com/biospot.html.

You shouldn't use the Hartz flea drops either because they can paralize or even kill cats. I still see many stores that still sell this terrible stuff.
