So, today, Yul (six months old neutered male) had a very atypical "mishap" for him. He's been perfectly clean from the moment he came into the house, through my changing the litter I used, the type of litter box, and having a terrier move in that's very interested in his toilet.
Today, as I was cleaning the box, Yul peed right in front of me on the rubber mat that's under the box. He does tend to "remember" he needs the toilet every time while I'm cleaning it, but he never "missed". I'm just hoping this isn't the start of a bad habit because he's been so perfect so far.
Any advice? Should I just keep him out of the room when I'm cleaning the box?
