Last year when our rabbit was terribly ill the Vet made sure Revolution was administered when she was admitted to the hospital for her first week long stay. So I would have to say it is good for even very weak animals. Just made my third purchase of this from petbucket because Annabelle has been thriving. She also has cat and dog sisters who are very chummy with her so she needs protection too.

Very happy with this stuff, I use it on four indoor/outdoor cats, I was having trouble with ear mites but not anymore, within two months no more head shaking and no more foot in the ear !!!

I've been buying my flea/tick/heartworm prevention treatment (Stronghold) for many years, and I've been super-satisfied with the product, the prices, and the company. They are very concerned that their customers are satisfied, and keep in touch regarding my satisfaction. They are the very best!
