I cleaned up Rambo's pen today. I opened up his house so it could air out, then I cleaned off his toys. I got rid of a couple of the toys he didn't play with, too. I also raked his house and made all the dirt nice and even instead of it being lumpy messy. I also gave him fresh water, cleaned up his bathroom corner, and filled up his busy ball for him to play with. He is really happy I cleaned it up!
