I am so sorry to hear of Ben's passing. My Prince died following a seizure almost 2 years ago, but he was alone in the vet's office when it happened. As painful as it must have been for you to watch, I'm sure Ben felt some measure of comfort knowing that you were there with him. Take comfort knowing that he is now seizure-free at the Bridge, running and playing with all the other furkids that went before (and after) him.
