Hi could somebody give me some advice please regarding my Sugarplum. She lives with us along with her brother & 6 other cats. Suddenly she has started wetting & pooping everywhere - I have thought that this maybe territorial but have noticed that if she gets a fright, her bowels & bladder just open. For example I was watching a horror film in bed & she was asleep at the end of the bed, the film made me jump which in turn made her jump & with that she peed & pooped all over bottom of my bed. However she knows she's doing wrong as she immediately flies downstairs & out the cat flap. Also another thing with her is that she is forever biting (or licking) herself down there to the point that it's almost obsessive. She has been deflead & wormed so I can rule out both of those. Would appreciate any answers, thank u!
