So sorry about your girls. My wife and I have talked about this in the past, all our pet were at the vets. When we got the news of OS with Brin, we decided to do right then and there, a deal we made with our boys a long time ago. Now with Blackie and Red they've come so close and the best of buds, they are never two feet away from each other, it's going to really hard one way or the other, but it will be at the vets. Last appointment of the day, far back office with his favorite puff and mommies pillow.
The worst, best of luck with your girls, sending lights and prayers
