Chomper was surrendered to us when his owners had a change of circumstances. Upon arrival we were told he had seen a vet due to something on his back and was informed it was age related. We decided to get a second opinion and it turns out it is a cyst that has turned aggressive and will need removing asap. He will hopefully be getting neutered while under the knife which will make his life a lot easier and he will be able to have some girls. Any donations are greatly appreciated and please share if you can. Thank you, Coastline Guinea Pig Sanctuary.
