Re Pichu's breed. He is definitely "Blue Sang" The girls that were playing with him outside when I took him told me that he was the pet of some of their neighbors and he's pure breed. I think I know why they got rid of him! He likes to scratch furniture. I try to teach him to use a piece of wood I have on the balcony and everytime he tries to scratch something, I take him to that spot and it seems to work, so far.
