So after 3 days of extremely hard work, ripping up carpet, laying down tile. Ferret proofing the closet, and making a swinging door for the door way, I finished my turned my spare room into the boys room last week. They love it, are doing great, hardly sleep in the cage at all since I leave it open now. The problem is.... As of yesterday my cat has decide to jump in and out of the room and use their extra litter boxes that are in corners. I don't know what his problem is, he has his own litter box, and a bigger one at that. I don't know if it's his way of retaliation of all the times they've tortured him or what, but I need an idea of how to get him to stop this........ anyone ever went through this and have some advice? lol
