They are recovering.
Last week noticed that Ninkasi has red scabby bits in the thin fur patches in front of her ears. Bet that's flea allergy dermatitis, thinks I. Somewhere there is a box with some spot on we got from the vet a few months ago.
Finds it, applies it on Saturday. Then reads leaflet and finds out it was wormer, not for fleas.
In my defence they've never had problem fleas before, but Pumpkin is always eating something that warrants worming.
Tonight I vacuumed and sprayed the top floor with flea killer.
Then get spot on flea stuff, shove it on both cats. Didn't manage to get it in exactly the right place apparently. (surprisingly difficult when they're disappearing down the back of Pingu's neck.) So they both manage to lick it and hypersalivate massively. Sorry kittehs.
