Sure, it's Polish.

Example, verbs:

"I was" in Polish - byłem (male) byłam (female) byłom (neither, not really in use, but technically correct).

Example, nouns:

"A cat" - kot (male), kotka (female).

"Kitty" - kotek (male), koteczka (female).

Then depending on cuteness informal obligatory rule gradient is:

koteczek (male) koteczka (female),

kitek (too cute for gender),

kituś (much too cute for gender),

kituniek (cuteness, love and sugar overload, gender does not exists in the universe, you have seen the face of god and they are bliss).

Works for every verb, but there are grammar rules and shitton of exceptions in the gradient.

Exit: I forgot to purr form kiciuś/kicia, and I have no idea where it should be on the gradient
