Our cat had completely 'groomed' nearly all of the fur from her entire belly and hind legs (ongoing over nearly 2 years). Our vet thought perhaps she was doing this because of stress/nerves, or food allergies. After reading some of the Spirit Essences product descriptions, I found there is actually a name for this problem - "Bald Belly Syndrome". We started giving our cat a squirt from the dropper (about 5 drops) once a day. She didn't mind the taste (I also rub any remaining fluid in the dropper around her ears). Initially I wasn't sure that it was going to work because she seemed to start grooming immediately after getting the drops. But within in a couple of weeks I noticed that the bare belly was now covered with short fur, and it continues to fill in week after week. Amazing! Whatever caused the problem, this product really helped!
