We put this flea collar on Molly our dog. It seems to be working ok. Probably will be buying 3 more for our other cats. I like the fact that there are no chemicals.
I got this yesterday and planned to gift it to a co-worker of mine who complains about her inside/outside cats always having fleas. She came into work today to tell me that after she bathed her cat and put this collar on him she has not seen a single flea on him all day. Normally they would be all over him in seconds but an entire day went by flea-less. She is so thrilled that she is going to be purchasing some herself this time.
This Collar has been working great for our dog.
I love these collars. They even last a little longer than supposed to.
