Hi, 2 of my guinea pig just died few days ago. They were about 3 month old. Before their death, they become very quiet, skinny ( u can feel the bones when you hold them), and barely move. Even if they are moving, they just drag their back leg along. They also lost their appetite. For info, I fed them with timothy hay, and other supp pallets. Not sure exactly what cause their death. Now, I got the same problem with the 3rd guinea pigs, and also the adult male. Do u have any idea on what have cause this? The adult female is healthy and not showing any health prob..
