It felt like they were different. In that year, the collars had a smell and the cats did not catch ticks. But the cats stubbornly scratched around the collar, although everything was in order with the coat. This year, the collars have stopped smelling, cats do not smell, but they do not scare away ticks at all. The expiration date was good on the packages. I can't comment on flea protection. They are not on cats, so it protects, probably.
