I have successfully litter boxed trained Cookie. I use a regular cat litter box and litter. I think I use Arm and Hammer brand. I will say that he doesn't always make it in. Sometimes when he feels like being lazy he puts his 2 front feet in a then pees (thought this is not very often). He always poops in it though. I would also say that he prefers to go outside but we live in Florida and it can be very hot to stand out there for 20 mins.
The way that I trained him was to keep putting him in it and telling him to go potty. When he would go I would praise him and give him a treat. The treats were only for when he would go potty. He would get one for pee-pee and two for poop. I do clean it everytime he goes. I have noticed that if he has peed in it and I don't clean it, he doesn't like to poop in it.
If you have anymore questions feel free to ask.
