They eat every plant from roses, to greenery, doesnt matter. Ive tried the Bitter Spray and it doesnt work.

your only option may be to give up on house plants (as I did for 17 1/2 yrs) as no home rememedy worked, and placing the plants up high only motivated the offender to jump to reach them- and he succeeded!

My dad uses cayenne pepper to keep the cat off the plants. Mix it with water and mist liberally.

try spraying the plants with bitter apple

You might want to try using the grass they sell at pet stores. My wife says cats need greens for proper digestion. I you give them grass, they might leave the plants alone.

there is a spray that is plant friendly, and pet friendly, but the smell turns cats off from plants.

if you catch them... spray them with a water bottle sprayer... or you can spray water/pepper on the plants leaves...

Clove oil deters them and smells nice too. Keep in mind that you may need to get rid of the plants if she keeps eating them, because many of them are toxic to cats. Check the aspca.com list.

I can't have plants either. Acutally I don't have a green thumb, lol. My thumb is actually black, hehe. My ex mother law puts orange peels in her plant pots. Cats hate citrusy stuff, plus this isn't a chemical that will harm your pets. Good luck.
