Part Manx kitten is incontinent
by Lynda cat mommy
Our part Manx kitten, is incontinent. Occasionally dribbles, but almost always, when he's sleeping. Covering his sleeping areas with the waterproof pads, is something I'm getting tired of washing. Help, our vet is looking into it for us. Tomorrow is the neutering day, so the vet seems to think he can check things out a little further then....
I can't say whether or not this is your kitty's problem, but...
Some Manx cats may suffer from neurological issues which are said to be related to a deformity with respect to the spine and the characteristic Manx "taillessness."
Some experience more problems than others, and there may be treatments depending upon the situation.
Although this has been refuted, some sources indicate that one of the possible symptoms of these problems is incontinence. I've posted a couple of links below which tell both sides of the story, but your vet is going to have to be the one to diagnose this.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1789620/
"It is hypothesized that the problems associated with the tailless condition such as spina bifida, urinary and faecal incontinence and locomotor disturbances of the pelvic limbs may all be related to a disturbance affecting the development of the central nervous system in the early embryonic life."Karello Cattery Manx cat mythsMed Helphttp://en.wikipedia.org/wiki/Manx_%28cat%29

I wish I could be of more help. Please come back and tell us what your vet says about his condition. I wish you the best.
