animagus fic

[qzee]

the story I am looking for has Harry as a teacher in Hogwarts and he transforms into a moose. Snape is depressed and learning how to change into his animal form is supposed to help him. He becomes something prickly, I think a hedgehog. A link to this story would be great.

Found by scabbyfish in mere seconds, it is "Learning to Uncurl by Amorette"
