Right now Griffin, my sweet boy is about 11 weeks old! I got him 2 weeks ago, and until I get him neutered (maybe Feb.?) I keep him in a x-pen with a variety of hidey homes, tunnels, toys and a big litter pan, when im at work or asleep. He was mostly litter trained when I got him...with only the occasional droppings around my living room area or under my Christmas tree so I am very happy with him and his good behavior! I haven't let him have run of the rest of my apartment yet, I feel like the area he has claimed now is manageable until any urges he will one day have of spraying until he's fixed.
Back to the topic of cleaning! His x-pen sits on top on 2 3' x 5' rugs I got at Home Depot, maybe $8-10 each, and that sits on top of a big piece of cardboard. I researched relentlessly on the flooring issue...coloroplast/chair floor mat/vinyl/ceramic/sheets/plastic-y table cloth, and the throwaway rugs are great for me (so far, its only been 2 weeks here!) and the price is ok. Since he keeps most poop in his box, I change that once a day. I use Yesterdays News compressed paper cat litter, and cover it with hay so he can munch and do his business. Its so easy to take a plastic bag, dumb everything, and refill. No worry of sticking on or smelling, or him digging and throwing the stuff everywhere! The routine is easy, certainly doesn't feel like a chore!
