Customers like the performance of the pet supplies. They say it is very effective when used properly, and starts working pretty quickly. It also works great in conjunction with monthly prevention. Customers also mention that the pills absolutely work and kill every flea on their bodies. They love this product because it works as advertised and doesn't make their cat sick. It is effective for 1 day on the pet, but once it gets in the fleas system it is effective forever.

Customers are mixed about the value of the pet supplies. Some mention that the price is worth every penny, while others say that it's expensive and a waste of time and money.

"...Because Capstar ONLY KILLS ADULT FLEAS on your pet and only works for 24-48 hours (a day or two) The young fleas, Flea egg and Larvae remain...." Read more

WOW, amazing!!
4 Stars
WOW, amazing!!
First let me state that this is NOT a cure-all or a preventative treatment!! It simply kills ADULT fleas that are ON the cat for a few hours/up to a day. My cat was suddenly infested and I was desperate!! II just gave the pill to my cat, and 20 mins later she was howling and jumping all over the place, and I see that there are already fleas on top of her fur and just falling off! I found her in the bathtub less than an hour later, frantically grooming herself, surrounded by dead fleas (see photos!!). I couldn't believe it. People who say it doesn't work are crazy! Lol. It works, but if you have fleas OFF your pet (outside, or carpet, or other untreated pets)....they will jump back on the next day!! So this must be used as part of a regimen. I took one star off because it's so dang expensive, over $4/pill! P.S. She calmed down after about an hour and a half. :)
