Ingrian (a Finnic language spoken by ~70 people in today's northwestern Russia; borrowed from another language, either Finnish, Swedish, or Russian if I had to guess)
Kven (a Finnic language spoken in today's northern Norway; inherited from Finnish kissa)
Swedish (as far as I can tell, it usually refers to female cats only in Swedish)
Russian ки́са is pronounced very similar to kissa, too (I don't know the etymology, though)

So it's two languages that are related to Finnish, Swedish (which is where Finnish borrowed the word from in the first place), and technically Russian. Maybe there are even more, but other than Russian, this set of languages makes sense to me. According to Wiktionary, the original Swedish "kissa" comes from "kiss", as in, a sound you make to call a cat. Kinda like "pstpstpst" but "kisskisskiss" instead.

I speak a bit of Swedish (it's the second official language of Finland) and I have never heard or seen anyone use kissa for cat, it's always katt. And apparently kissa also means "to pee" in Swedish, kinda funny lol

That's interesting, thanks for letting me know! I don't speak any Swedish, so I have to rely on dictionaries when it comes to stuff like this. The Wiktionary page says "kissa" is the feminine version of "kisse", but both are "colloquial, endearing", so it's probably not an everyday word used in casual conversations. And yes, cat and pee being the same word is funny :3c
