I don't know of any tests, but I got a cheap one about 5 years ago for about 10 - 15 dollars. My two cats are (and before I got the zapper, were) mostly indoor cats which get some outside time with my supervision. Before I got the zapper, I had a serious flea problem, having to spray the cats and bomb the apartment at least once every two weeks to keep it somewhat under control (ie., so I didn't get a lot of flea bites myself). After I got the zapper, I have only had to bomb the apartment once or twice (I don't remember, but I know I bombed it the day after I got the zapper, and am not sure if I ever had to after that), and sprayed my cats once (the day I got the zapper). I haven't found a flea in the apartment since then. Of course, it may have been that the flea population decided it didn't like the neighborhood anymore ;->, but I doubt it. -- ------------------------------------------------------------------------------ Dave Gotwisner UUCP: ...!unisoft!peritek!dig Peritek Corporation ...!vsi1!peritek!dig 5550 Redwood Road Oakland, CA 94619 Phone: 1-415-531-6500 Brought to you by Super Global Mega Corp .com
