Yeah, Tubby has done this too, except sometimes I don't get the pleasure of it being poop - yes, a nice huge puddle, first on the wall then down to the floor. I had been thinking it was because he was getting older with maybe a touch of arthritis and he couldn't squat as much as he used to, but most times he gets it in the box and it's only sometimes he misses. I don't know, maybe he's distracted, in a hurry or just lazy. The good news is the litter boxes are in our unfinished basement, so it's not too much of a problem.
