Mefite sarastro's having a cat/flea situation, but in verse: "What remedies exist for a cat beflea'd?"
My most faithful feline associate
while I, at length, was absent
has, it seems, become woefully beset
by fleas or lice
or something that bites and leaves
her in a most agitated and sorry state.
And so on. And the answers follow suit, in large part. Cat question in, doggerel out.
