hi! i am new here, and am needing to know if anyone has a recipe for or know of a good product that i can buy, for spraying on my house plants when i bring them in for the winter, that will keep my "kitten from hell" away from them? thanks for any help.

You might try a little bit of blood meal on the soil of one plant and see what happens.

What about using garlic/hot pepper powders?

My cat absolutely HATES galic/pepper tea. That's what keeps her out of my plants. And yet she loves to sit smack in the middle of my chives. I guess onions are yummy to her. I have also had some people tell me that putting fresh or dried orange peels on top of the soil worked for them. A lot of cats hate citrus smell, so I hear, but my cat was raised around it so she doesn't even flinch.

A cheap grocery store astringent (beauty products) in a spray bottle works great! May be necessary to reapply - but just dab a little on your finger for him to smell and watch his reaction!
