Having Amadeus Euthanised

The needle was curved. (Why was the needle curved?)
The vet daubed the spot with alcohol where
In a moment he would administer the overdose.
Why bother with alcohol? In a minute my little cat
Would be dead – no danger of infection there.
I asked for a plastic bag. They were nicely obliging, but
When I got home and opened the box, look at this:
They’d given me a clear one. Great. This was the sight
I’d hoped to be spared: him, curled up, still warm,
But not breathing. Before proceeding any further,
I put down the shovel to go get a black one. Glad.
