Darin I'm so pleased you 've got a vet coming to the house to help Blanca on her final trip to Rainbow Bridge.
I certainly don't think you were crazy - I reckon it's a normal reaction to someone having to prepare a much loved furkid.
We did this for our sweet Siamese Kisi - and when the time comes to say 'Goodbye' to our present furkids I will definately repeat this and have our vet visit the house. Yes it's more expensive, but so worth it.
I'll be holding Blanca and your wife and yourself in my thoughts.
