What does it mean? It looks like something to turn nouns into adjectives, but so far I've only seen it in things that could have been possessive phrase. Is there a difference between -ин and using the ordinary genitive case?

Semantically I do not see any difference. The suffix -ин
is used to express posessiveness.
So:
кошкин дом = дом кошки
мамин дом = дом мамы
Grammatically you can't add more attributes to cat or mother because they've become an attribute themselves.
дом моей мамы = ?
дом серой кошки = ?
Also you can't form possessive adjectives that way freely. There are many exceptions and other ways to express possessiveness:
Петька - петькин
Катька - катькин (and other names formed like this apply for this rule)
Нина - нинин
лиса - лисий
заяц - заячий
So if you have nothing else to add about mother
, go ahead and use мамин
.
This is analogous to the two ways of expressing possession in English:
mother's house vs. the house of the mother
мамин дом vs. дом мамы
