One of the neighbor's cat, prefers a certain area in my backyard to do its dirty business. Anyway, I'de like a pet detecting device that will spray the cat with mace spray, hopefully something unharmful yet effective for it to run away. At first I was thinking of a giant mousetrap for cats, but that means you have to clean up a dead cat, plus I like cats they are nice quiet pets as long as they are in my neighbors area.-- romanmar, Nov 30 2004 Cat territories http://www.vin.com/...PR05000/PR00025.htmHit and miss, meow, hiss and piss [normzone, Nov 30 2004] Have you tried Google? http://www.google.c...terrent&btnG=SearchCat Deterrents [Letsbuildafort, Nov 30 2004] Cats don't like this, http://www.primrose...php?p=sp0011&r=GOOGCats don't like this at all!

Kitty learns once, kitty learns good.-- DocBrown, Dec 01 2004 How about a pop-up sprinkler head attached to a motion sensor? Kitty comes in, kitty gets sprayed, kitty goes away.-- Freefall, Dec 01 2004 I vote for [Freefall]'s idea.....non-lethal cat deterrent technology is fun stuff.....In warm weather I'll throw water on the occasional agressor.-- normzone, Dec 01 2004 Remember the laser kitty toy? Have a laser pointer, make it really strong and visible during the day, and drive the cat crazy.-- DesertFox, Dec 02 2004 But you can get cat repellant stuff that you put down on your lawn or one of the linked electronical devices. This idea is redundant - widely known to exist.-- harderthanjesus, Dec 02 2004 Being a vet's assistant, this title scared me. Thanks for not giving the mace to the cats.-- stilgar, Dec 03 2004 random, halfbakery
