The RSPCA UK shared the story of how this newborn kitten was found, along with a short video of her being bottle fed and getting stronger so she can thrive, saying:
A member of the public opened his van in central London and found 3 newborn kittens inside with no sign of their mother.
They were so young to be without their mother and sadly two of the kittens haven’t made it – but this last little girl is a fighter and doing well. Here she is being hand-fed.
