I'm so sorry for your loss. It's worse not knowing the cause as well. It sounds like you got her the best care possible. Sometimes it's just time, or there's something the doctors can't see. I'm glad that her bond-buddy is getting some extra attention too. In the last 6 months I've lost two hamsters without any real indication that they were ill, and had a necropsy come back inconclusive as well. It's so scary not knowing whether it was something you could have prevented, whether or not it's contagious, etc. Just know that you did your very best for her, and the vet did their best for her as well. Binky free, Chloe.
