Having a huge problem with the buns of late. They keep peeing on the living room carpet, so much so that cleaning it is no longer working and stains still remain. I have no idea what got into these guys (I suspect its Xena) as they never peed on the carpet before. So now we're trying to figure out what to do design wise in the living room. Meanwhile we've gone back to basics and locked the buns back up until they learn their proper litter box. I truly don't think its an issue of not having enough litter boxes. They also pee on the bathroom mat and that's located maybe 6ft away from their den. They don't pee on the hallway carpet which is right next to their den. I guess its just one of those strange things but **** I wish I could figure it out so I don't have to throw out any more carpets and won't have my family upset that they can't get nice things.
