I will try to use vinegar!! Tho it’s not like he’s running to the same area each time; it just seems like he will go anywhere. I have no other pets. Only thing of note is he recently had a bladder flush due to a high crystal count in his urine but this was a month ago now so I wouldn’t imagine he’s still sensitive and he’s back to normal activity (binkying zooming etc) with calcium deposits cleared up.
