Why is my 10-week-old kitten peeing on the sofa then using the box?

Pet's info: Cat | Domestic Shorthair | Male | unneutered | 2 months and 13 days old | 5 lbs

I have a 10 week old kitten. I got him when he was about 7 weeks old, he was a stray. I had to litter train him myself. He was using his litter box just fine. Sometime last week he started peeing on my sofa and then running upstairs to the litter box to use it. What could it possibly be? I have three other males, all neutered and they all get along great.

I had this exact same thing happen to me when my kitten was young. He would get so busy playing that he would "forget" to pee and when he finally couldn't hold it anymore, he would have to run to the litterbox. I found that I would have to take my kitten to the litter box every couple of hours just to "remind" him to use it for a few weeks until he got older. I suspect it is just immaturity, but certainly if it continues to happen as he gets older, have your vet evalate a urine sample to make sure there isn't something medical going on. The other thing would be to make sure that Merlin has a litterbox readily available since upstairs can sometimes be too far for a kitten. Good luck! I hope that was helpful.
