“my cat is allergic to fleas and this medication was recommended by our vet. She just started so I don't know what the long term affects will be but for the mean time she is comfortable and no longer losing hair.”
“I have two rescue cats that due to one being abused and the other was a feral, I cannot put topicals on them. Comfortis can be crushed and added to food. The results are immediate and lasting. I highly recommend.”
“The product works great!! Been having a terrible flea infestation on my dog, probably because our backyard is adjacent to a huge canyon where coyotes and rabbits are and the weather in San Diego is just perfect for fleas to live. I' used to use Comfortis and it seemed to work before, but I tried changing to PetArmor from Costco because it was cheaper and was easier to get because I didn't need to go to the vet for a Rx. PetArmor didn't work, then I tried FrontLine, but that didn't do anything and I had enough of having my dog suffer all summer and fleas infesting the house so I tried Comfortis again and it worked like a charm. She stopped scratching, she stopped smelling, her skin irritations went away. TL;DR, Comfortis is awesome and way better than topical treatments.”
