How do you keep cats away from your house?
I think if you put crushed garlics into your watering can, then
water around the edges of your garden, then this scent will deter
your feline pests.
We use to 1/2 FILL A CLEAR bottle with water and lay them around
the house about 50 meters apart cat's will approach it but never
come back. Something to do with seeing there reflection in the
bottle but i really don't know, but failing that you can take a
dead starfish from the beach and they smell the ammonia coming from
it and take off
