Laura Diegnan. A vet has performed rare caesarean section surgery - on a GUINEA PIG. See SWNS story SWBRguinea. Vet surgeon Sarah Jane Kenny operated on the tiny pet and delivered six kits despite the risk of using a general anaesthetic. C-Sections on guinea pigs are rarely successful even by the most qualified vets familiar with the animals because of their size. Nugget, a pregnant one-year-old guinea pig, arrived at MyVet Firhouse in Dublin experiencing serious difficulties during labour.
