He might have a uti if he is peeing on your floor. If it's not a uti - then maybe he wasn't shown how to use the litter box by his kitty mama (or his breeder?) When he pees - clean it up with the appropriate cleaners or if you catch him - grab him up and put him in the litter box. I've gotten peed on a couple times... and was the unfortunat to have Hali poo on me once - but it was something I had to teach him. He uses the litter box faithfully now.
Also - is he neautered? Did they miss a testicle? He might be peeing due to that - but I would think the area would be wider if he was territorial.
Since it is summer he will be shedding a lot more and hairballs will be a way of life.
Try brushing him more or try different meathods to get the extra fluff off of him to reduce the amount - but they will still happen anyway.
P.S. Perisans ARE
high maintenance - I'm sure everyone who has one can say that.
They have super tangly hair that can matt up in front of your eyes when it's shedding season. Depending on their faces, you have to clean their cheeks and eyes from the tears and eye crud. The hair around their butts can be ruined by runny or even hard poo that either needs to be cliped out or wiped off. They also require more baths than usual to keep up with that luxurious fur. Then you have to do the general cat stuff - clipping those claws, cleaning the ears and brushing their teeth. Anyone who says Persians aren't high maintenence have either never had one - or don't mind the mess and care.
I'm one of the people who don't mind the mess or time to take care of them.
So I will say - nope - they are no work at all! But I do know the difference in work between my dsh and my persians and they definitly need more work than he ever will.
