How can you list those but not furaffinity?
That one aside you might wanna specify what you mean with "tf" as there's a massive difference between a human growing cat ears and a tail then continuing to have fairly normal sex, and an already furry character in a furry world being turned into a limbless latex doll then inflated to be used as a blimp. Pixiv has catgirls galore and some furry stuff but you'll be seeing most options on kemono already.
Either way tfgamessite probably has something but it's not dedicated to furry either. Eka portal technically focuses on vore but seems to have a lot of furry content too.
But honestly if you can't find what you want on e621, EH, kemono or FA you need to give a lot more specific info.
