I put my cactus outdoors on our patio in the summer. We live in a semi-rural area in Ohio and have alot of wildlife, especially squirrels. The squirrels come on the patio and dig in my cactus pots, uprooting them and some times eating them. I have gravel around most of them, to no avail. Is there something I can sprinkle in the pots to deter them?
