My healthy young bunny died suddenly. Was an infection the cause?

Updated On September 23rd, 2025

Pet's info: Small Animal | Rabbit | Male | unneutered | 3 months and 15 days old

I had a healthy and happy 3 month old bunny. He was always curious and playful. Yesterday, he suddenly became lethargic and developed weak legs. He then collapsed; and while collapsed he ran in place. He then seized multiple times and died. He was sneezing last week, and he had conjunctivitis (non-purulent) for 2 days, followed by rhinorrhea which started yesterday, but my vet reassured me. Could the infection have killed him? How can I raise rabbits to live long?

Sorry about Atheistan. A severe respiratory infection (penumonia,rhinitis) such as Pasteurella, could have lead to sepsis and invasion of the brain. This could have resulted into rear paresis, seizures and death. There are several other infectious diseases possible and a necropsy (post mortem examination) would lead to answers. Good luck.
