I recently adopted a 7 weeks old, white, female Persian kitten. Her paws, hind legs, a portion of her tail and the upper part of the fur on her body are stained yellow-brown. Her caretaker used to put her in a cage, so she must have walked or rolled around in her own urine at some point. I’m wondering what I should do to remove it. Should I wash her with whitening shampoo or trim the stained portion or should I just let it be? Will it go away on its own? The little kitten isn’t really the best groomer, I even had to clean her little booty myself when she defecated.
