Capstar Flea Tablets for Dogs & Cats 2-25 lbs is rated 4.4 out of 5 by 215.
Rated 5 out of 5 by from Kill fleas for 24 hours Capstar works great. But, fleas can hatch again and again. What is needed is a no prescription 30 flea killer pill like Comfortis. I have 3 indoor feral cats that cannot tolerate a trip to the vet. Additionally, the expense of the vet bill and prescription is prohibitive. At least Capstar provides them with some relief.

Rated 5 out of 5 by from Works very well Have used capstan for years, back when you had to get them from the vet. Was glad to find them on chewy.com I have informed my friends where they can buy them.

Rated 5 out of 5 by from Half the price of my vet I am fostering a nursing mom and her babies and she needed a flea product. I bought some from my vet but then decided to check on Chewy. 1/2 the price! Yay!

Rated 5 out of 5 by from Good Stuff This really works when your pet has picked up fleas, and you just want to kill them all before you use your flea treatment.

Rated 5 out of 5 by from Loving this product so far I bought this product for my kitties along with the same item/larger dose for my slightly heftier dog. Previous use of topical treatments were ineffective and seemed to make my kitties lethargic and grumpy. I know you're laughing and wondering how I could tell, as grumpy and lethargic is typical kitty behavior, but it was really noticeable. Getting the kitties to swallow the pill is a bit more difficult than with the dog (as in I had to be forceful and paid for it when they knocked EVERYTHING off of my dresser in retaliation later that evening). However, the product works well with no mess and no noticable side effects. You still have to treat bedding and home with other products, but this is a great first step. My little angel-devils were free of fleas within 24 hours. I know that an infestation is frustrating, but you can overcome it. I strongly recommend starting here. Once you break the life cycle of the fleas with this product, a little bit of diligence in housekeeping will have your home flea-free. Good luck!

Rated 4 out of 5 by from It's ok I have 5 yorkies ranging from 2 lbs to 10 lbs, 2-9 years of age. I think this worked ok. They haven't had any fleas that I have seen since taking the pill.
