- Hartz UltraGuard ProMax Flea & Tick Collar for Cats & Kittens I 14 Months Protection I Soft & Comfortable | Kills Fleas, Ticks, and Larvae I 2 Pack

This collar works for my inside outside cat Ziggy. This collar is Ziggy approved (see picture). She is a long hair cat and the fleas were on her in one day outside. I put this collar on her and the fleas were dying then gone within 3 days. Never once saw a tick on her and my wife and I check her often. We live in a wooded area and fleas and ticks are a real issue. When we took her to the vet for her maintenance shots the vet scoffed at this collar saying none of them work. I don't care if he's a doctor he's still wrong and wrong is wrong. Buy this collar!

Virtually no ticks this year. Very pleased. My cats don't mind these collars at all. No smell or gross liquid. Highly recommended, you won't be disappointed

I literally just received these and while slightly familiar with the features of this collar, i done messed up during the activation. I broke one within seconds at the 'BREAKAWAY while stretching it as per the directions, which should include a emphasis to be careful of that point of the collar. Hartz, please for the sake of others, update your instructions. Otherwise, having just appling the collar i have no further input, but have had success with Hartz products in the past. If i feel inclined will update this review with better feedback on its effectiveness.

My cat got fleas, topical treatment didn't seem to work so I decided to try a flea collar. Put it on the cat, the fleas persist even though the collar says they should be dead in a day. I decide to give it a few days, more fleas than ever. A cat simply overflowing with fleas. Bought a Seresto flea collar to replace it. The fleas were all dead in a day, no more fleas on the cat. This is very much a you get what you pay for situation. I tried to cheap out with these, two collars for $30 or so against $60 for a single Seresto collar, but all that's gotten me is it costing $90 to get rid of the fleas instead of $60. Skip these, buy a Seresto one.

I’ve had this on my cat for a little over a month and I have been pleasantly surprised. So far I have not noticed a single stray flea when she comes inside, despite the fact that there was recently a flea hatch out in one of the spots she frequently visits (yes this is being handled as well). And the only thing I noticed is it does have an odor, but it isn’t overwhelming by any means. I will stress that anyone who uses this product read the instructions. I don’t believe you are supposed to medicate your animal on top of placing the flea collar on them (this means insuring any prior medication is well out of their system). It seems such errors have caused issues with animals like those mentioned within this comment thread (one of my biggest concerns w/ this product). However, my cat did not become ill in any way following the application.

Why did you pick this product vs others?: I don’t think this brand is good as Sreto Sreto really gets rid of the fleas, but I still noticed getting bit by fleas with this Heart’s Brand even though I shampooed and vacuumed my floor. I’m still getting bit by fleas and both of my cats have this collar on it’s supposed to last for Six months or so. I know that Soresto does but to me I’m noticing that hearts doesn’t really work as well as Sreto.

These collars are great. My two kitties have been flea free going on 6 months. I will buy again. Setup a subscription, and I only do that if I am impressed with a product.

They do ok at flea removal, but not great. It has to be used with other things, so I think the $5 flea collar does just as well. Won't buy this version next time, as the value to price is just not there at $30. They are durable, but have some overall issues with effectiveness.
