My daughter went out to her cages before and found 2 mothers, 8 babies and a pregnant guinea pig all dead. She is absolutely devestated as she also lost 2 rabbits yesterday and now has 9 baby rabbits to care for. She said the guinea pigs where fine this morning. The guinea pigs in with her rabbits are fine but all the ones in the other hutch are all dead with no signs of why they have died. The only survivor of the trauma is a one little guinea pig that was born blind in one eye a couple of days ago. Would anyone know of anything that could wipe out so many animals in just a few hours without showing any sort of symptons?
