when i say punish her i never hit her lol (wouldnt have it in me), when i have caught her in the act ive picked her up and put her in the tray then shut her in that room till she uses it.
Her paws are fine, we regularly check them as she did have an ingrowing claw when we got her.
As for excessive toilet use, she eats about 4 trays of food aday- is that right ?, she would eat more if i let her....
