I have little Gracie peeing in her kennel everyday.  She doesn't have  UTI. She pees on her bed, so I removed the bed.  She pees in the pan and will lay in it!  She gets plenty of opportunities to go outside any time she wants and when everybody elso goes outside, too.  I can onlly assume this is a female marking issue?  I would like opinions on how to get her to stop this behavior. I have an indoor "pack" of one intact male 18 moonths, one spayed female, 4 years old, Fergie and Gracie are ltter mates and 14 months old. Gracie is the dominate, sneaky one instigating trouble; if it happens she most likley started it. Diana is the eldest, but nice to all.  The male ignores all the playing and fighting and usually ends up snoozing.  Thanks again for any advice.
