I am sorry that the lil' fellow didn't make it, but remember, you tried your best. He is now hopping on the Rainbow Bridge with his bunny friends. He is eating the lush grass and nibbling on the endless piles of fresh carrots. The water is crystal clear and he has all the hay he could dream of! You will meet again, one day. Chin up. You did good and he knows you just tried to help. RIP lil' bunny.
