Well when kittens are going through maturity from kittens to cats they are getting ready to reproduce, so their hormones start to go crazy and males and females will urinate . Male cats will become aggressive with other male cats, females will pee and advertise their hot and ready lol. when reached maturity they go through heating which is when the female is the most fertile and is purring and even more affectionate, urinatinting so other males can know shes available. and they howl loud meowing
