It should be safe for both.

 

I found bitter lime in my pet store and sprayed it on the plastic curtains that Egypt has a penchant for chewing on. It didn't work at all. I still found countless little holes in the curtains. Hope you have better luck with it.

 

I mixed the bitter apple with listerine and put Rico near it after it was just sprayed on the cords. It only took a couple of times for me to do that,and he now leaves the cords alone. Every now and then I will reapply it,but I've had good luck so far.

 

I had a foster kitten for the shelter who had a raw spot she wouldn't leave alone (three legged amputee post-surgery). The shelter's vet tech gave me bitter apple spray to put on her. It should be fine for cats.

Also, when I last had my cats in to the vet about 2 weeks ago, I decided to buy some bitter apple for my guy who licks himself bald. I bought it for my cats and the vet knew this, but the packaging only talks about dogs. So I've now been given bitter apple for cats by two separate vets/techs.

 

They seem to market Bitter Apple for dogs, but it's safe for cats.

 

Thanks everyone. I'm going to see about getting getting a small bottle of each tomorrow.
