"HI! Kiwi here. I jump up on the couches alot, which I don't see a problem with, but my owners do. Here is a natural spray you can make at home to keep your cat away from couches, chairs, and tables."
What you need:
1 cup boiling water
1 Tablespoon Rosemary
1 tsp. lavender
1 tsp. Cayenne powder
Directions: in a medium sized bowl, pour in all ingredients into bowl and stir. Let sit for 15-20 minutes and let cool. Drain and pour liquid into spray bottle (I just got mine from Dollarama). Spray onto surfaces you don't want cat to be on.
