I took care of a puppy (for a local shelter) that looked exactly like your new dog, markings and everything. I called him Professor Peabody von Poopsalot, because well he did.
Awww shit, those first two pics made me sad. What a sweet 'lil thing. This'll probably sound ridiculous, but in the last pic the look in the kitten's eyes seems to be saying 'thank you'.
My cats are rescue shelter cats, the thought of animals being mistreated, abandoned or dumped breaks my heart. I look at them now and still can't believe that someone, along with their sister whom another family adopted, just dumped them in a banana crate by the roadside where some far more responsible person found them and took them to the RSPCA.
