There are what I think are cecal smears on the floor. It happens while I am asleep and in the same 2 spots on the kitchen floor. I see no actual poos or cecal and her bum is perfectly clean. She is acting her normal self. She does all her poos in her litter box and they look normal. Has anyone seen this before or have any ideas what could be going on? She has had no real changes to her diet. Should I be concerned?
