I was in so much trouble. But happily things have improved in the time it's taken me to post. Even though I've totally failed in my objective.
DH is out for the evening ETA unknown.
DD and I brought feral outside farm kitten in to worm. This is a strictly outside cat farm. DH doesn't do inside cats ever.
Feral kitten promptly disappears down behind the kitchen units.
Catch big outside cat who has never been inside before. He promptly disappears under side board cupboard thing. But comes out for food. He can hear kitten so calls her. She's is squeaking away but is now somewhere deeper behind cupboard and he can't work it out.
20 mins later big cat has had kitten food, warmed smoked mackerel pâté and has persuaded kitten out. No one has been wormed but at least everyone is out before DH discovers the cat chaos I've created.
