Please don't feel bad about this. It is obvious just from your first post requesting prayers for Midas that he was loved with all your heart. Animals can't tell us what is wrong, that can't tell us when they hurt, that is unfortunate, but true. As Smoke said WE and more important MIDAS knows you did the best you could for him. He is happy again and running and playing just like that Rainbow Bridge poem says. They gave that to me at the vet when I lost Scottie too, and I believe it.
This is a loss for your family and you need to grieve through it. We are here, but please don't feel bad, you loved him and he loved you and that is what matters.
