Discovered 2 weeks ago that my elderly and seldom venture in to the back yard cats had fleas. This is a first for us, as they dont really go anywhere to pick them up iyswim. Anyway, got them some frontline and have treated them both, also got some nuvan staykill and have sprayed everywhere in the house, including my mattress twice!!! But I am still being bitten, relentlessy. My legs look absolutely disgusting and I feel really grotty and grubby, not to mention itch like hell! The cats aren't even scratching anymore ffs!!! Can anyone suggest anything please?
