What do you all use to combat the smell in the indoor cage. As fast as I clean Pippa's tray and corner, she pees again and the pee stinks! Looking at people who have 4 or more house buns I can't believe they all smell as bad! At the moment I use newspaper but she tends to shred it then pee on it. She's going outside soon but I'd love a lionhead for a housebun but OH says the smell's too bad and I should stick to the indoor piggies Is there a secret to an urine-odour eater?
