Cat peed on my bed.

My neutered male cat has peed on my bed twice now. I've had him for almost a year and everything was fine. I adopted him when he was a kitten and he gets along very well with my other cat. I live in a small space and have a litter box that they share in the bathroom. It is large and covered and i clean it every other day. The first time this happened I came into the bedroom right after he did it and was able to grab the comforter and wash it before it touched the bed. Same with this last time. I was on the bed when he was meowing in the room and then jumped on the bed and kept meowing and i looked over and he was squating like he was about to pee. So he got him off the bed and brought him in the bathroom by his litter box- he didn't seem interested in going in. I cleaned it in front of him and he still didnt go in and then a few minutes later i walked in the room and there was pee on the bed. A LOT. I dont know if this is behavioral or if something is wrong with him. Sometimes i think he has cabin fever and just wants more space and is being a little jerk about it but i just dont know. I need to fix it now though! I've had cats all my life and have never had a cat go anywhere but the litter box.
