Frontline ineffective
Bought a bottle of frontline spray 100ml lot nr. X01409A with expiry date 02-2023 and sprayed my 2 cats and 1 kitten and it was totally ineffective. No fleas died, none left the cats no change at all. It was like spraying water. I have used frontline before and found it to be an amazing product so was wondering if there might be a problem with this batch
