I have a piggy that is 5 months old. I've only had him for a couple weeks now and I love him to death, but the poor little thing is half white and has alot of white fur on his underside. My problem is he keeps peeing inside of one of the pvc pipes thats in my boys cage and then he just lays in it. So then he's all full of pee and is stinky and gross! How can I get him to stop this? Is it because he is still young? And should I give him a bath after he does it everytime? His hair is turning yellow on his tummy, any ways to stop this too? TIA!
