hmmm I don't know much but I have two:
'Biting the Tiger' this is kinda what your talking about. it's yaoi and two characters are able to turn into animals. there is some fantasy in it too. it's pretty cool!
' Like cat and dog' this is about headbands/product with cat ears and dog ears. It's also yaoi, and for mature audiences so yeah... aka it's smutty
I don't know anymore (I might, but I can't list them off at the top of my head) but you can go to the topics and look at supernatural/fantasy... maybe there will be something that you can find? Hope I helped! (▰˘◡˘▰)
omg thanks so muchhh
ofc! :)) hope I helped
im currently looking for shoujo mangas or webtoons like neko to kiss. or domething similar even if possible without the whole animal thingy,
