Oliver is considered a diffuse tabby. While his dominate color is gray, he has white socks, and a hint of yellow on his tummy and the inside of his legs. His fur is soft, sleek, and very short.

Oliver is a very friendly and loving little cat. He loves to run and play with the other cats in his foster house. Despite being little he is not intimidate by larger animals. He is friendly to dogs once he knows they are not going to eat him. He does have some skittishness due to his life as an orphan on the mean streets of Franklinton, but he is still willing to quickly trust and love in return. He has idiopathic cystitis so its important that he only eat canned Royal Canin SO.
