Hartz UltraGuard Flea & Tick Collar for Cats and Kittens, 7 Month Flea and Tick Protection and Prevention, White

It seemed to work for a day and flea bites on the cat's neck were gone but it stopped working after the first day.I used flea shampoo, flea spot on, sprayed the bedding, and used organic DE (diatomaceous earth) with it, nothing seemed to work.The fleas kept coming back, and I had to keep flea-shampooing the cat to kill the clinging fleas. So it must be the flea eggs that are so hard to get rid of. I may fog the house as a last resort.DE usually works well for fleas but for some reason, it doesn't do anything for fleas (even in the outside yard where they kept hopping onto my legs within one second of getting out of the car).

I bought two for my cats for most part works well if they leave it on or alone. But it assists in flea and tick control east to use have to cut to size if need be . Quality price and easy to use.

This review is for the specific product that I purchased, Hartz UltraGuard Flea & Tick Collar for Cats and Kittens. My complaint is with the product itself and not Amazon. I bought these collars for both of my cats and both of my dogs as a preventative measure. None of them showed signs of fleas or ticks but we have recently moved to a new state where there are stray cats out and about, along with a lot of other insects that were not at our old home and state. Both of my cats are inside cats, trained to be on leashes, walk, sleep and typically stay near us. However, we bought them because I do take my dogs outside and we feared our dogs catching fleas and bringing them into our cats.I purchased them on August 30, 2022 and received them on September 1, 2022. I put them on all of my animals as the package instructed. I left enough room for 1-2 fingers to fit under the collar to ensure they weren't too tight. In the few days after, we noticed that the cats had strong, foul smelling feces. More than usual. One of my cats vomited a few times but we didn't think much of it. Maybe the cats ate something when we didn't see them or something like that. I never thought that the collar would be the culprit (I still don't know if it is but it's a big coincidence). Until today, September 6, 2022. My cats came to lay with me and I noticed one had a large bald spot near his neck. The hair wasn't thin or thinning, it was completely bald. I then moved the collar and saw that it was completely bald under where the collar was. Additionally, parts of it were extremely red and raw while other parts looked dry like skin was flaking off. I checked the other cat and it was the same thing only not as bad. The hair underneath the collar of my other cat was gone as well but the skin didn't look as bad. I immediately removed the collars and wrote Hartz. I received an email very quickly from them which is a plus I guess. I called the number in the email and eventually spoke to a poison control center that they forwarded me to. They in turn said that they share my report and finding not only with the company Hartz, but a report will be generated to the Environmental Protection Agency.My dogs seem ok but I will remove the collars from them too as a precaution. The poison control center gave me a direct number to reach them at 24/7 in case anything else develops or doesn't get better. Unfortunately as stated above, I just moved to a new state with my family, tens of thousands of dollars to attend an internship at a hospital here that is unpaid so, not only do I not have veterinarian here, I currently don't have the funds for that. The lady at the poison control center said that if I had to go the veterinarian, I would have to pay and then contact Hartz and they may be able to help me with the costs. All I can do now is hope that my cats get better. When asked about recovery, the lady at the poison control center said that depending on the cats, it could take weeks, up to years for their hair to grow back if it does at all.This is frustrating because not only did I pay a lot of money for my cats, having them flown in from another country, but because we love them as part of our family. Buyer beware with this product and I hope none of you have this issue. Oh, FYI my cats are pure bread Oriental Shorthair so I don't know if it's a breed specific thing or what. Hope this helps someone.

I ran the flea comb a couple passes, and a cat had a lot of fleas. I stopped, because they said that this will instantly start killing the fleas. Today less than 24 hours later, I decided to run to flea comb through the cat again. Most areas I didn't get any, and one area I got two fleas. I even combed her back half, and it was pretty much flea free. Now I'm working on getting the fleas out of the house. I was trying to get rid of them first, but they said you got to get the host cleaned up first. I don't think she's going to miss her little friends. 😆

I use this on my indoor cat, as a preventative measure for fleas & ticks. I can't see spending $50-$60 dollars for the expensive name brand collar for a strictly indoor cat. I do however have 2 indoor/outdoor dogs, so this collar works great to help protect my cat from any fleas and ticks that may may make their way inside on my dogs.I've never had any problems while using it. And I generally replace it every 9 months. It fits well, and my cat ignores it so it must be comfortable for her. Lol!I can't speak for outdoor cats, but for indoor cat owners this is a great, affordable option.
