I went to Petsmart today and bought my babies a litterbox with a cover and swinging door. I put it together in front of them so they would see the litter before I put the cover on. I guess I could've made things easier if I had left the swing door off for awhile, but I didn't think about it. So now we have this new thing in the cat room and Neo is very curious. The first thing he does is sniff all the way around it, I guess looking for a way in. I pushed open the door for him and let it swing shut. He began to paw around the sides of the door. After a couple of very pitiful looks, I picked him up and gently pushed him through the door. He was in! But, he's too smart for his own good. He understood that the door went IN to let him in, so it must go IN to let him out. He extended his claws and got them through the side of the door to grip the door and pull it in towards him. He couldn't get a grip and you could tell he was getting frustrated. I obviously couldn't show him the way out the same way I showed him in, but I pushed the door enough for it to swing in and out so I could catch it and open it for him OUT for him to see it goes both directions. It took him a good 10 minutes to figure it out, but he never cried for help, so I let him think it through. I'm a little worried about Sapphire, though, because there are times I think she's a little retarded, bless her heart, and I'm not sure she'll get it before she has to poo again. She didn't stick around to watch Neo figure it out. I figure I'll just watch for poo on the floor and take the door off it it becomes a problem. Any suggestions on making this transition easier?
