Animal transformation fics are different from traditional "creature" fics (such as veelas, vampires, and werewolves) as in the latter cases the character is usually considered not-quite-human. And even in their 'human' form they will have heightened senses or additional powers and such. No, here they are just temporarily transformed into an unremarkable animal, whether by choice or by curse.

As I was putting this list together I realized that this trope is most often used as part of an "Identity Unknown" type plot. In the fics recced below, it turns out it's always Harry who transforms into some sort of animal, and Draco who is temporarily clueless as to his true identity.

Now that I think about it, this is the opposite direction of deception as in my previous sets of Identity Unknown recs, where Harry is more often the clueless one. This may or may not be significant. Hmmm....

While the transformation is most often due to Harry's being an Animagus, sometimes it's caused by a curse instead. Either way, Draco isn't able to figure it out right away, which is part of the fun :)
