Lexa eats little kitties. Tastes almost like little bunnies she says.
We have no cats in the backyard veggie gardens, and any feline that passes through the front yard is very quick and very wary.
The little kitty from the neighbour's (they don't seem to give it any loving) adopted our daughter, and is the only cat Lexa tolerates even a little bit. No idea were Bob the Cat shits or sprays, but so far it's not anywhere in our yard. Best of both worlds I say.
