I was really keen on trying this product, as it has a really good mechanism in terms of how it repels the ticks/fleas. In an ideal world, this is ideal for cats that suffer from Flea Allergy Dermatitis, as the insects are repelled and shouldn't/cannot bite the cat.
HOWEVER, both my cats could not tolerate the collar, despite fitment as instructed, My cats both became itchy and had mild reactions to the collar. Sadly, I cannot recommend this collar for sensitive cats.
