Dont encourage her to piss in her cage... thats her bed... a place to relax away from the hustle and bustle.....
Never use the cage in a negative way.... if shes done something bad... dont put her in the cage.... or she will associate it...that when shes in there she has done something wrong....
I toiled trained mine...and the youngster is 95% there.... by taking them out every 15 mins....
When they wake up from a sleep...OUT...
when they have drank....OUT...
when they have ate... OUT...
And every 15 mins or so inbetween...
It will take a few weeks...with a lot of accidents
