DO NOT USE SENTRY NATURAL DEFENSE FLEA DROPS FOR CATS! [View all]

[TexasBushwhacker]

These drops have only "natural" ingredients like peppermint oil, clove oil, etc. My roommate put some on her cat, between the shoulders as directed. It is very smelly and the cat freaked out. Later she vomited in both our bedrooms so we washed it off as best we could. She's been drinking and eating very little and is very lethargic. I started looking up reviews on places like Amazon and found that lots of people have had problems. A few cats have died!

There are some complaints for the dog version as well, but mostly that it's ineffective and causes hair loss.
