Turkish Van kittens & cats in Gustine, California

This is Nug, short for Nugget. We have had him since he was a kitten, he is now about 2 1/2 years old. He has always been very playful & loving, very vocal. He’s good with babies, kids, & strangers. He was generally well behaved around other cats he came into contact with. In the past several months we have come across some behaviors that we don’t know how to prevent, such as urinating in our clothes and making a mess out of our trash. It only progressed into him urinating in our baby’s belongings. I want to be clear that he is not a “bad” cat, i’m just not equipped to train him out of these behaviors. I also feel he’d be happier if he had more space/freedom, as we live with others and he cannot always have full home access. He’s full of affection for everyone and always willing to play. Sidenote: I am unsure of his actual breed, and had to make an educated guess.
