What owners say
Buy if you hate fleas
I have used this product for over 6 years with no issues. It does what it says, keeps fleas and ticks away and extremely easy to put on. The price is a little high you may think, but seeing as this lasts 8 months, it’s worth the money. I had a serious flea issue in my neighborhood but after my dogs and cats got this, we had zero fleas inside our home. It gives off no scent and you forget they have it on at times because it doesn’t have the stick or greasy feel like other flea collars do.

Bar none the best!
My cat was immune to ALL flea drops! From the most expensive down! He was miserable and still had fleas. As a last resort I ordered this collar even tho it was so expensive. Hallelujah! It worked! Took maybe 3 days but it worked! All his hair is growing back from him chewing on himself and all the (TMI) scabby areas are gone Yea, it’s spendy but supposed to work for 7-8 months so it is comparable to drops in price. I and Seamus (the cat) are forever in your debt. Thank you Seresto!

Good flea collar- but doesn't last 8mos.
I really loved this product. My cats were really sensitive to the drops so I was glad to find this product. It worked well and didnt bother them. But I have noticed that it doesn't work for 8 months anymore. I had to replace 2 months early-. (I put the reminder on my calendar.) My poor kitty has fleas. My daughter noticed the same with her dog's collar.
