BBC News Published image copyrightRSPCA image captionWest Hatch Animal Centre in Somerset has 36 mice - 33 adult females and three babies More than 130 mice, known for being prolific breeders, have been rescued from the same house. The Natal Multimammate mice, found in Atherstone, Warwickshire, were not neutered or separated by sex "so the situation spiralled out of control", the RSPCA said. The breed have "many more nipples than a standard mouse," the charity said, meaning they can breed often and have large litters. They are now in need of new homes. RSPCA inspectors were called to the property on 18 April after concerns were raised about the mice being kept in poor conditions.
