Five stars. Our cat had a bad attack of the fleas in the hot summer of 2013 and we were given this flea collar by our vet. It worked and has been working ever since. Never had a single flea issue since.

Absolute lifesaver! A mild wet winter here in France seemed to make the fleas totally resistant to everything we tried. All the different spot ons from the vets would work for a few days then we’d be back to itching cats. Our girl was totally plagued with an allergic reaction to them. I hadn’t tried Seresto because both hadn’t tolerated flea collars in the past and it seemed to be the same drug as one we had already tried, but on vet’s recommendation we thought anything was worth trying. Well, both tolerated us putting on the collars - both difficult to handle girl and scaredy-cat boy (they are rescues with history!), and they were comfortable within an hour or so and have been fine ever since. Now six weeks later, girl’s hair all grown back and she’s putting on condition again. And no ticks! Added bonus! Just wish there was something similar for horses! Do not hesitate, these collars are brilliant.

I bought one of these collars last Summer for my cat who suffered badly from flea excema where just one bite caused eruptions on her skin. Since using this collar she has been completely free of fleas and her coat is smooth and shiny. I am now ordering a new one as I have been so pleased with these results.I would urge anyone who has a cat with a similar problem to invest in this product .
