Hello everyone. I'm looking for some transformation manga. What I mean is human to other species, be it furry or feral or monster girl/guy. I know of Ranma 1/2 and Fruits Basket. I'm also looking for monster girl mangas besides Monster Musume and Centaur's life and 12 Beast. Thank you.

Kindan no Koi de Ikou + 2 1 volume prequels (Werewolf, not sure if that counts as what you want)
EDIT: Now that I think about it... I think he is a wolf that turns into a human...

First story of Bokura no Himitsu o Kyouyuu Shiyou ka with a sequel Bokura no Himitsu o Kaihou Shiyou ka (human to catgirl +others)

Kanokon (Various human/animal/youkai transformations)

Yami no Purple Eye (Transforms into a panther)

Amairo Islenauts (Various monster girls)

~4400 manga completed
~1700 ongoing...

How about Youkai Shoujo - Monsuga? Just came out this year, but I haven't read it myself.
