I read about doing this somewhere. While I am waiting for my weapons grade ant killer to arrive in the mail, I still have to feed the cats. And since I am not going to go around and spray the cracks and crevices they are coming out of for now, I have to find alternatives. NOT leaving cat food out during the day is simply not an option.
So - cat food meets the pie plate.
The theory being that ants can't swim, although I'm not convinced mine can't, if I keep a moat of water around the bowl that holds the food, they will not invade it. Cats will just have to get used to it.
Doesn't seem to bother Riley.
And as for the ants that wander in - well, this baby won't be put away for a while.
Survival of the fittest. Or the thinking-est. Or somethin'.
