My rabbit died suddenly and peacefully. What could be the cause?

Pet's info: Small Animal | Rabbit | Male | unneutered | 9 months and 7 days old | 12 lbs

Sadly my rabbit passed away a few weeks ago. One day he was perfectly fine and playing, but the next day he was lifeless and passed away. His death seemed very peaceful, and I was wondering what could have been the cause. I wasn't there but I was told he was very calm and didn't seize or anything. He just was laying there and then he was gone.

I am very sorry for the loss of Mozart. Without a physical exam or a post mortem exam, it would be almost impossible to determine why he passed away. It could have been anything from a toxicity to something congenital since he passed so quickly. Rabbits, being prey animals, are quite adept at concealing illness until they are very sick. Take solace in knowing that he likely did not suffer.
