As my hubby is desperatly allergic to cats, I had resorted to poison. When I would start seeing them, I woudl toss lots of poison anywhere they dogs coudln't reach.
Then, about a year ago, some road construction displaced some feral cats - right into my yard!!!! There are two of them, a gray and white one and an orange one. I have never gotten within 25 feet of either of them, but they stick around and take care of my rat problem.
Because of the rats and the racoons, there is no where I can leave them food, or I would. They are slowly teaching my dogs that they don't liek to be chased.
Althogh I don't have the horses at home, I do have goats, so I have feed - I leave the feed door open so the cats can stalk anywhere they want! I love my feral cats!!!!
