I have a cat fancier living two doors down from me. He refills the food bowls in his garage often, consequently there are always six or eight cats lounging in his front yard.
His hobby ruined mine. The cats come down here to hunt and kill birds so I had to stop feeding them and take down their nests. The cats leave their scat and spray in my garden and flowerbeds, so I plowed them under. My grand children can't go outside and play because of the filth.
I've taken up a new hobby, cat trapping, and it seems to be working very efficiently with his hobby now. He attracts the cats, I trap them. The hobby keeps me exercised carrying them to the humane society to be put down. I may have to buy another Havahart trap, I caught two in one day last week.
