My veterinarian said that the flea %26 tick collar (this collar from Hartz) is not healthy for your cat.

Terrible Product
AprilJul 3, 2026
It does not kill or repel anything! I followed all the instructions as this type of collar is not new to my cats.
Didn't work

This didn't do anything for our kitten. My husband said the reviews were good, but I haven't looked and I can't see this having good reviews. Please spend your money on something else.
Didn't work for my cats

Very disappointed in this product. Says it's supposed to last 7 months, pfft, yeah right. I was brushing my cat this evening so I removed the collar to find bites directly underneath it around her neck. The flea comb revealed live fleas on her and she's been wearing it over a week. Waste of hard earned money.

because again it never came in my order like it says it did. I've been trying to get flea products delivered to me for a month now. I pay for them and I never receive them. it's really not ok. My cats are suffering, I'm disabled and need them delivered to me. I'm very very upset. I placed these in my order because they weren't supposed to be delayed like the even more expensive ones I ordered at least a month ago. Then I was told it was held at the Groton CT. PO at customers request. I never requested that along with 2 other items and the pO said it was never there. I'm pretty aggravated.
DO NOT BUY!!!

Be careful

I bought this collar for my cats and unfortunately after using it one of my cats had a seizure and died. So please make sure your cat can handle it. ❤️‍🩹🥺
Not the best collar for fleas
RLSep 22, 2023
I'm afraid I have to give this a lower rating. The collar only lasted around 14 days, not 14 months. I purchased many and was unsatisfied.
HOW DID THIS GET ANY OTHER THAN 1 STAR!!
TRACEYMar 25, 2023
this is impossible to put in either of my cats. Three people have tried to get it to go thru the buckle and it will not! What a waste of $30.00!!
MelissaJul 3, 2022
These do not work. I bought four of these. I put the collars on my cats and after a full day and a half, nothing. The product claims on the packaging that the collar begins killing fleas, ticks, flea eggs and larvae immediately however that is not the case. I will be returning all four.
