First things first -
to YT --
So glad you joined our family.
I am sorry little Chloe is having this problem. I have never experienced it - I am sure that others will post after me with other ideas - here are mine. If she hasn't had a check-up with her vet lately, that is always a good place to start.
Do you "watch" her when she urinates - and what happens immediately after? Could she be losing her balance and falling into her urine? Or could she be rolling in it?
The only other idea I have is that if she has long hair when she squats the outside leg hair can act as a wick and soak up the pool of urine. This happens with my Lacie who has a floor length coat if her leg hair isn't pulled up in a ponytail.
