Kitten peeing in bed?

Hi everyone! I’d really just appreciate some insight / advice and any sharing of experiences would be great.

I’ve had my kitten Celeste for about 3 weeks now, and she is approximately 10 weeks old. When I first brought her home she took to the litter box fairly well. Despite one or two accidents on the floor (never stools, thankfully, just urine) whenever I would place her in the box, she knew what to do. It only took her a few days to start using it on her own. I had initially placed it in a very obvious spot in the living room so she wouldn’t have any trouble finding it. Once she got older, I moved it to a more private, conspicous area and showed it to her — she has had no trouble finding it in the new spot.

There were a few occasions when we first brought her home that, although she was using the litter box, she did also pee in our bed when we had her up with us. As quickly as possible we would remove her, show her the litter box (where she would finish her business) and then spray the sheets with enzyme cleaner and remove them to be washed (with oxi clean!) She did this about twice, but it was when we first brought her home and she was still only about 7 weeks. We figured this was just an accident because she was too busy playing on the bed and couldn’t get to the box in time.

We got another litter box and put it in the bedroom for when she is in there with us at night, and she does use it. We now have two litter boxes and use non-clumping clay litter (only because she is in a phase where she likes to play and put some of it in her mouth). We clean the boxes regularly, but I like to leave a small amount of urine sometimes so she knows where to go.

She got really good with the box after we got the second one and always went inside of it. No more floor accidents and not one in the bed either. We began letting her up with us much more often (and sometimes we couldn’t control it anyhow because she had learned to climb up on her own 😆 and liked sleeping with us).

Recently, however, she urinated on the bed again. This was two days ago. We washed with enzyme cleaner again and changed the sheets. I’m a little disappointed because she went so long without doing this. Is this normal? Was it likely just an accident because she’s still a kitten? She’s been using the litter box really well but I suppose it’s still a possibility. My girlfriend did say that she was sitting by her litter box, so she stuck her hand out to her to see if she wanted to come and hang with her — she did walk to her — so she picked her up and put her on the bed — and that’s when she peed. Maybe she got confused?

I just hope she doesn’t decide that the bed is also a place she is allowed to go. I think I’ve done most of the suggestions for litter box training. Any advice? Even just reassurance that this is normal would be great. 🙂
