awww...poor baby. Yea you can just see the dirt and ick on her belly...poor baby. The mouth thing does NOT look good at all, she definetly needs to see a vet soon.
Also and I am sure you already know this....but feed her something a little smaller the first couple of times as not to shock her system. Sorry...I know....I have the total mommy syndrom...lol...
Way way good on your for the rescue!!!
