GREMAG Cat Flea and Tick Collar, 8 Months Effective Protection - Adjustable Cat Flea Treatment Collar Waterproof for Cats Puppies

This thing is luminous at night, we don't have problems about that. For its efficacy, i can say it kept fleas away at the start. I believe it still has some efficacy but it's not the dry season anymore it rains everyday and it keeps flea population under control in the garden. So it might be combination of factors

Disappointed it doesn’t glow as advertised as I have a nearly black cat and can’t always see if she’s outside waiting to come inside BUT after trying many things to try and rid the dreaded fleas this collar seems to have been the most effective so I’d still recommend it’s just a shame it doesn’t glow.

I've previously bought a very similar collar for £30 that worked wonders, thought this collar might be just as good, but just cheaper.Collar has been on the cat a few days and it seems to be working so far, no irritation showing so far, and no fleas either. But the smell of the collar is horrendous. You can smell it before you even see the cat. I don't know if I'll be putting up with it much longer if the smell doesn't start to disappate soon. Rather spend more money for me and my cat to be comfortable

Best flea collar I have ever bought, highly scented would recommend.

Ok but doesn't glow, not sure if it does keep the fleas of as the cat still keeps scratching quite regularly..

They are working well would buy again

Always buy the same product, works well and worth the money

It lights up, but needs additional treatment for fleas applied, not really effective otherwise
