I tried all of the above except for the cat hair. What I found effective was hot pepper wax which I purchased at a garden store. Spray it on. Or Repels All. They really helped! (I may have used them both!)
Another tried and true method is to scatter mothballs around your plants. The rabbits and chipmunks won't bother any of your plants. The drawback is that the mothballs don't release a very pleasant fragrance!
Helen, I tried cayenne pepper too without any success. Other remedies recommended to me that I've tried without any luck were sprinkling human hair over the plants, as well as blood meal. HOWEVER, the thing that DID work was cat hair! I brushed my cats and sprinkled their fur over the plants and the critters did NOT like that! If you think about it, it gives off the scent of a predator and I supposed that's why they then stayed away. Good luck!
