Hello we are new to caring for Guinea pigs, we bought two at Easter and lost one about 1 month ago... No idea why, we came home and he was lifeless, took him straight to the vet but he died on the way. We sought advice from 3 or 4 pet shops and were advised to by another pair... They integrated really well with our remaining Guinea pig and the three have been really happy... However I came home last night to the same thing... 1 was lifeless, and after I cuddled him for around 30 minutes to see if there was anything I could do (it was around midnight) he also passed away. I have read very carefully on what to feed them and how to care for them and have no idea what or if we are doing wrong... They have a two storey hutch outside along with a run that they use in the shade in the day, we clean them out weekly, they have fresh food and water daily and lots of cuddles, we feed them specific Guinea pig food combined with lettuce and veg... I am really worried about the other two, has this happened to anyone else?
