While cats are not usually as destructive to your garden as dogs, they can still be pesky. Cats can defecate in your garden, attempt to pounce on a bird that’s on top of a tomato plant and tear the whole thing down, and while their digging isn’t as bad as a dogs, it still does harm. If there is a cat digging in your garden, try adding sharp, pokey things into the ground, such as pine needles. The scarecrow sprinkler, which I talked about yesterday in the dog article, will also repel cats. Catnip and cat grass are also a way to give your cat an alternative to being in your garden.
