Writing four-legged Ted's name on the label, she happily posted the gift.
And when the courier attempted to deliver the package, Brittany wasn't in.
She noticed the little red card of doom when she came home, and planned to pick the missed item up from her local post office in Kentish Town, London.
But when she turned up with the card, post office meanies turned her away empty-handed.
Apparently, 'Ted Maher-Kirk' aka her cat, was required to come into the post office himself and provide identification. Otherwise, he wouldn't be allowed to pick up the packet.
Baffled Brittany wrote on Facebook: "I've got to ring up the Post Office Head Office and explain that my mother has sent the cat an advent calendar, addressed to the cat, and he can't pop in to pick it up himself or lend me his ID to do it for him…"
Metro.co.uk reported they have contacted the Post Office to see if they are willing to bend the rules for Ted.
