my guinea pig stopped eating and drinking water he hasn’t moved from his hut. I took him the vet yesterday and the checkup was all ok but the vet I go to does not do blood tests and X-rays. I gave him some food and water in a syringe yesterday. I gave him some water today in a syringe and he started to twitch it sounded like he was choking/ going to throw up. He stopped twitching and settled so I put him back in his hut and he started making strange noises very husky sounding noise. Does anybody have any advice as to what this might be. He is 3.5 years old and there is a strange smell coming from him and discharge.
