Barb'ry,

Multiple Mudcatters supplied your gifts
My clue is vague but to one 'tis a swift
Reminder of a hobby to fill quiet days
I scooped up for a song (the Mudcat Auction says)
The Lion needs to keep his roar to himself
Until all is revealed by our tidy Kat Elf.

(I tried first for "ululations to himself", but that's a tough one to rhyme or make scan!)

Your Secret Santa (who visits the post elf first thing on Monday)
