It is good and i like that it does not have strong smell of other products. Have a real old cat and she has no problem using it. It seems to work but of course fleas are very hard to keep under control.

It Works

We have 4 cats but the products we had used in the past for our flea problem quit working. We switched to Cheristin and it has done a great job getting rid of the fleas. Our cats are so much happier and no longer constantly scratching. We would recommend to give it a try.

fleas beware!

Wonderful product for eliminating fleas. I wish it lasted longer and that it was a bit easier to apply. Our cat seems to sense what's coming -- maybe she smells it -- and gets quite squirmy and it isn't the easiest thing to part the hair on her neck and apply the product.

Happy With Cheristin & EntirelyPets
July 4, 2017
I've used Cheristin on my cats for about a year, and so far it has been effective at eliminating fleas in my multi-cat household. I only recently found EntirelyPets. They have the best prices, and orders have arrived fast with no issues at all. I recommend the product and the website.

Best For My Sensitive Cats
June 6, 2017
I had been searching everywhere for something to replace Activyl that was on back order indefinitely. I have 4 cats 3 of which are very sensitive to almost every kind of flea preventative med out there. So took a chance on Cheristin. Not one of the cats had a bad reaction to it. No fleas either. Was slightly greasy in their fur for a few days but not really a problem. Even when you follow directions and part the hair it is going to run a little so expect that but again not a problem. Will continue to use as it seems to be as good if not better than the Activyl.

Vet said she thought the flea med I was using on my cat wasn't working very well and she recommended Cheristin. It has been amazing! Great product, great price from EntirelyPets and fast shipping.

Great Product
June 3, 2017
I have 6 cats in my household, 3 are mine and 3 taking care of for a friend. The cats I was taking care of where staying in my garage. A couple of months ago they became infested with fleas. One cat we almost lost had to take her to vet. She had so many fleas on her that the fleas sucked blood till she almost died. 3 days in the vets office and vet recommended Cheristin. Worked so well we use it on all the cats now.

My Vet uses this--but---he said to only use 3 times then stop----so that is what I do---works great--better than any other thing out there--if you don't live where it freezes in winter, you have fleas---never had them in the mountains--and I had 35 cats---

Great product. I prefer it to Frontline or Advantage. There are no fleas on my cars here in Florida.

Solved my flea problem!
April 27, 2017
I have 5 cats and had been a satisfied Revolution and Atvantage Multi user for years. Both products just quit working for my cats around 6 months ago. I tried several other products that were highly rated and nothing was working until I tried Cheristin. I've been applying monthly for 3 months now and no fleas since 1st applications. I'm sorry it doesn't address the other issues like Adv Multi and Revolution used to but at least the gang is flea-free once again. Also, no loss of hair or irritation at the application site which happened occasionally with the other products so that's great too.

Best flea product I have tried on my cats; it's quite effective. Also, the odor is not as offensive as other flea meds and it does not seem to irritate their skin the way other products do. I highly recommend this product.
