What can I mix in the soil of my flower box to deter my kittens from using it as a potty?

I have an 12 foot flower box outside of my bedroom windows (it runs across the front wall of my house), I also have 2 6-month old kittens who insist on using it as a litter box. Now the front of my house smells incredibly bad whenever you get near the front door. I have plastic flowers inbedded in the box so theres no living organisms in danger of losing life, but I don%26#039;t want any harm to come to the kittens. I thought mixing coffee grounds might deter them and help with the smell, but if theres something else as harmless to use I%26#039;m open to the idea.

You could try adding a few drops of menthol or oil of eucalyptus as cats really dislike the smell. Alternatively, put something like small rocks or pine cones over the soil so that they can%26#039;t get dig in it.
Reply:You can cover the soil with pinecones or a thick layer of sharp white rocks.
Reply:I%26#039;ve heard cats hate the smell of oranges, so you could put some orange skins in there, and they also hate anything really strong smelling like eucalyptus or menthol. Just don%26#039;t use ammonia! It smells like cat pee to them and they will want to mark it with their own pee.
Reply:I have used black pepper in my flower boxes. It burns their noses and makes them sneeze. Cats smell before they dig.
Reply:I would suggest covering the soil with river rocks, they are inexpensive and look nice. The cats wont want to scratch in there with the rocks on top.
Reply:Don%26#039;t mix the litter with the soil as that will just reinforce that behaviour. Cover the open areas with rocks or a screen to keep them out of it.
Reply:Start with a fresh flower box. The old one will have the odors of the cats%26#039; waste products embedded in it.





Once you set up your new flower box, crush some clay pots and put the sharp edges of the clay bits on top of the soil (you crush the clay pots by placing them on newspaper, wrapping the newspaper around the pots, and smashing them with a hammer). That should deter the kitties from getting into the flower box. Don%26#039;t bury the crushed clay bits - just place them on top of the soil.





Good luck!
