Hi new to the forum and looking for advice please, I have two rescue guinea pigs I have had for nearly a year they are both male who have always lived together they are about 3 years old. One of them stop eating and very quite took it to the vet teeth etc checked, had injections and medicine and I hand-fed it with a syringe for a week, for the last week he has started eating and is slowly putting weight back on he did lose a lot of weight. He has been living on his own whilst poorly so I could monitor what he was eating etc think he needs another week on his own to put more weight on etc other GP is a big chap. Will I be able to put them back together and if so the best way to do it.
