So very sorry, I can relate to your experience and pain.
We've all lost precious ones and in time, we live again. We laugh again. And we keep on loving the animals that are left and let new ones reach our hearts again. I'm so sorry for your loss, for the ones who lost their best friends, for the way your sweet ones left their bodies and for the guilt you carry.
Animals have an understanding about death we humans don't seem to want to learn. Please don't blame yourself. Sometimes things are meant to happen as they did and no one is at fault.
Hoping the best for your sister as well.
