Or possibly an ASBO?
The fucker keeps coming into our garden and beating up our cat. She's small and adorable and he's a big black and white thug. Last time was before Christmas and she had a few scratches but was okay; this time there's a massive bloody gash on her ear, so vet tomorrow. Poor little thing! She's our baby and we are v v protective of her.
It wouldn't be unreasonable to send the boys round, would it?
(To be fair, I suspect she does the cat equivalent of, "Get out of my garden! Get the fuck out right now or I'll... Oh, wait.")
