Critter Deterrent

Critter Deterrent
Our neighborhood, like many in the states I imagine, is crawling with feral cats. For the most part, I don't mind them; they keep the pigeon population down, they don't cause a lot of damage or raise much ruckus. (I do wish they would quit reproducing, though) We managed to rescue a kitten recently and she is adapting well to her new, cushier life LOL

Unfortunately, there is one male that insists on marking our front door. Every. Freaking. Night. There are few smells in the world more pungent than that left by a territorial cat. My boyfriend was at the end of his rope and wanted to trap the cat to turn over to animal control - a solution that didn't sit well to me as I know that amounts to a death sentence. So, to the drawing board where I came up with my pressure switch triggered Sonic Critter Deterrent. It went off 4-5 times the first night, and we haven't seen or smelled the cat since.

Believe it or not (to turn a phrase) I live in Mexico and we don't have a problem with feral cats (I hesitate to speculate why exactly) but I do have a problem with a neighbor's cat who comes around to "visit" my little "Baby", so any harsh control methods would be frowned upon.
Your solution sounds like a perfect solution to my problem, and I'll give it a go.

I don't know what part of Mexico your in. There is a feral dog problem in some parts. You probably know but they run in packs and they don't look anything like the dogs people keep as pets. I'm thinking that is the reason for not having feral cats. They probably kill them.

I'm really glad you found a way to just scare him off without hurting him. I'm a cat lover. I do agree that ferel cats are a problem. They need to be neutered. They spread diseases to house cats that are let outside. This is one reason mine don't go outside. The smell from a male cat spraying is hard to get rid of. Before I got my boy fixed he sprayed several of my dresses and jackets. White vinegar diluted with water will take care of the smell he left on the porch. I'd say 1 part vinegar to 4 parts water. For clothing a 1/2 cup of white vinegar in the wash gets the smell out.

The best way to stop that smell is to just neuter the cat. Feral cats are an epidemic but only the community can get it under control. $20 feral cat sterilization at your local SPCA. A lot easier.

we also have boy cat scent problems. My wife found that although very stinky it is water soluble!So when our front steps or any other area gets the spray she uses my watering can and just goes around the porch at cats rear height and sprinkles it away. I will use your trick though on the neighbor brats that think 2am and 2pm are the same:)
