I have two cats, can both of them have collar on at the same time?
Answer by ChewyDec 12, 2021
Each pet should have their own individual collar for it to be effective. It is important to note that this bundle includes a dog collar and cat collar, which are not interchangeable between species.

Was terrible for our 5 year old cat.

We got these for our cat and our dog. Our cat loves to go outside and just lay in the grass so I figured we would get her one to. It left an open wound and hair lose around her neck and the collar and lose not tight at all. More lose then her regular collar even which I did take off just to have the flea collar on. Our dog does fine with it nothing I have noticed noticed I with him just her. I am very disappointed in it because of this issue. Would not recommend this to a fellow cat parent.

Be careful!!!

I just took in two adult cats and bought them these collars. It worked great on one cat but on the other it irritated her neck so bad that she lost some fur and had a massive irritation around her neck. Took to the vet and they advised me not to use on my cats but my dogs use them and I have never had an issue. Maybe the formula was too strong for the one cat. The other cat was fine but as a precaution I am sending both back. Chewy was helpful in sending me a return label for a refund.

Wow. Excellent

Chewy refunded me for the dog collar which was my fault for not reading the special correctly. They asked me to donate it to a shelter and I will be happy to do so. Thank You.

Hooray Seresto

After Frontline products no longer worked, we reverted to disgusting smelling dangerous sprays for the fleas. That is, until our daughter told us about Seresto. Thank goodness for Seresto. Within a couple weeks no more fleas and each collar is effective for 8 months. No more messy and dangerous monthly liquid applications that are actually more expensive than a Seresto collar. Hooray.

It works!!!

This stuff is the only stuff that works for our cat. And even though it says to replace every 8 months, ours has been working for a year. Cannot say much about the dog version, because my precious too-smart-for-her-own-good doggo tore it to shreds within a day. Yay....

seresto is not working on my cat

I don't understand...in the past I have gotten Seresto from chewy and they worked great- they got rid of the fleas on my animals. This time my cat still has fleas...it's been a week and she is still covered in fleas. I don't know what I am going to do. I thought seresto was the best.

Might be fake

I have used these collars for years. These last ones I ordered here haven't been effective. Still have fleas on both my lab and cat. Not sure if it's a bad batch or they changed the formula, but for the price Im not impressed and won't be buying another. Buyers use caution.
