A veterinarian to the stars is claiming that diva Mariah Carey is refusing to pay her $37,790.32 bill that she racked up on services and care for her pups Cha-Cha, Dolomite and JJ. Dr. Cindy Bressler filed a lawsuit which claims she tended to the dogs at their home of the singer, between October and December of last year. Carey agreed to the sum, but has only paid $8,231.50, and is refusing to hand over any more, according to the NY Post. Carey's lawyers have not commented, saying only that they were unaware of a lawsuit, and Bressler's lawyers have declined to elaborate on the dogs' treatment. But Mimi's dogs are used to A-list treatment... even if they can't get in to first class.
