Cookie died
She died peacefully of old age.
Here are some pictures of her before she died

Cookie was a great guinea pig and I loved her so much. She had a rough start but, I took her in and she had a great life. Sure she bit people every now and then but, she was a sweet guinea and a keeper. She lived a long 5 years and died peacefully. Brindle laid with her and kept her warm even after she died. We know this because when we picked her up she was very warm. I think Brindle just wanted to be with her because she knew what was coming. This was the final chapter of Cookie's life and the final chapter of her story. This book has officially ended no more updates from now on. R. I. P. Cookie

Your wings were ready but my heart was not. May you find a Golden Corral in Heaven filled with vegetables and all kinds of other guinea pigs. I hope you are happy where you are now. I am sad to see you go. I will never forget you and neither will Brindle because we both love you and care about you. Peaceful rest.
