Iv stupidly put the dogs flea treatment on the cat they’re both frontline and I didn’t check the packet!! Spoke to the vet who advised to wash it off and keep an eye on him said he should be fine as frontline is one of the mildest ones and he’s a large cat over 5kg - only the cat ran straight out of the cat flap before I even realised what I’d done so please someone just reassure me he’ll be ok. I keep calling him hoping he’ll come back so I can wash it off. I feel so terrible incase iv poisoned him.
