I'm really sorry to hear about this. My bunny who passed away last year look exactly like yours, except that he was a lop-eared bunny. His name was Bobtail. We went through operation after operation with him cos he had a very bad tooth and jaw infection, and countless nursing 24/7 but he passed away at only 2.5 years old. His daughter, Honeygirl, who was perfectly healthy grieved to death when he didn't come back and she literally starved and willed herself to die. She was only 1.5 years old. They were abandoned and we adopted them and looked after them so well and then this happened. It was so painful and traumatic I never thought I would get over it. Like you, my wailing was so loud and strangled when it did happen. You are not alone, we are grieving with you.
