Kitten and litterbox

So I got an adorable kitten Frankenstein a month ago. He's very well behaved, so sweet, and everyone loves him, including our other cat Arnold who hates other cats. But he's recently started misbehaving. We have a litterbox in my bathroom with a top on it that they both use most of the time (Arnold all the time) and use it perfectly. We have another one in my bedroom that we put there when we first got Frankenstein and were training him. A week and a half ago he stopped using it for a few days, so I took it away. He didn't like that. Pooped in my bedroom on my coat. So I put it back. Now he's started pulling all of the litter out of the box and onto the carpet. Including the poo. I don't think there was too much litter in there, but I'm going to try and see if that is the problem.

Any advice for me?

I would definately have two litters boxes with two cats. The rule of thumb is one box per cat plus one. So three boxes for two cats. However, I have two cats and two litter boxes and everything is fine.

Kittens sometimes play in the litter box. Very annoying for us humans who clean up the mess. You might set the litter box down into a wider cardboard box with high sides. Cut a hole in the side of the cardboard box. The hole should be low enough the kitten can still climb in but the box will contain most of the mess when the Frankenstein starts throwing litter around.
