Try a combination of citrus peels and moth balls.

Plant catnip and cat mint in an area where they are allowed to go.

Dig out a two by two area and replace the dirt with sand - thus providing them with a specific area to poo. Be sure to clean this out often, so they will continue to use this space and not other areas of the garden.

Plant rue, as cats d not like it...nor do they like thorny plants.

Do not use cayenne pepper with kittens. If they should get it on themselves and lick it, they cannot get the pepper out of their mouths! It is a cruel method to use for dogs or cats!

Hope this helps.

Moth balls help. Cats do not like the smell of citrus. My friend throws orange and banana peels around her plants, and the cats don't go there.

A permanent fix is to go to a feed store and get chicken wire and lay that down. Then place a thin layer of mulch over that. Believe me, they won't scratch there.

Mothballs or cayenne pepper

My mom always used moth balls, they worked pretty well.

Cayenne pepper....
