Hello! So this morning I found a stain in my room that I am pretty sure wasn't there before. I have no idea when or how it got there but it was dry by the time I started cleaning it up with some enzyme cleaner I have. But I can't figure out if my kitten urinated or threw up or if it was something else. I got down on my hands and knees () to sniff but it didn't seem to smell like cat urine , it just had a weird smell. He also hasn't had any accidents since I've had him (we're going on 3 months together, he is 4 months). When I cleaned it up, it came out a yellow/brown color... I think if it had been urine, I would've smelled it right away but I'm not sure. He has a vet appointment soon and if it's bile/throw up, then I'd like to bring it up. Thank you!
