Bunnybear by Andrea J. Loney
Plot Summary: Although Bunnybear was born a bear, he feels more like a bunny. He prefers bouncing in the thicket to tramping in the forest, and in his heart he's fluffy and tiny, like a rabbit, instead of burly and loud, like a bear. The other bears don't understand him, and neither do the bunnies. Will Bunnybear ever find a friend who likes him just the way he is?

This story is about a bear that feels like a bunny and a bunny that feels like a bear making a little space together to be whatever they want to be. At the end of the day, each goes home with their respective families (and species) and gets accepted for who they are. You could definitely take this as an allegory for being trans or simply a story about expressing your inner personality.
