Last night, my guinea pig ,Ella , started to feel very weak. I tried to give her food but she won't really eat. Today, this morning, I found her dead in her cage. I knew that she was soon going to die ever since my other guinea pig, Hana, died from old age. Sorry if I don't really reply to messages for a while.
Here's a picture of Ella (Left is Ella and right is Hana):
