Why are my rabbits dying suddenly in my rabbitry with no symptoms?

I am very sorry to hear about the sudden death of your rabbits. Unfortunately, without a true post-mortem examination, making a positive determination of cause of death will be impossible. In general, some causes of sudden death in seemingly health rabbits would include cardiac abnormalities, poisoning, and ingestion of a foreign objection resulting in choking or bleeding. Since you recently moved them to another pen and multiple bunnies died, my suspicion is that a toxin could be involved. I would inspect the area thoroughly for any unusual plants or objects. I would also be curious to know if the pen could have been accessed by other wildlife, potentially even something venomous or poisonous. Once again I am very sorry. I hope this helps a little bit.

I'm so sorry you lost your bunny. Please accept my condolences. Unfortunately, seemingly sudden death can happen in rabbits but without a post-mortem examination (necropsy) then the best we can do is guess at the possibilities. Now, I don't have his entire history so some of these things may not relate to him but typically this is the list we go by: 1. heatstroke 2. heart attack (can happen from underlying disease or a severe fright) 3. viral or bacterial disease 4. toxin ingestion 5. underlying kidney or liver problem 6. GI stasis (the GI tract stop moving) 7. heavy intestinal parasites burden 8. cancer 9. old age (could he be older than you thought) I didn't see that your vet did anything wrong or prescribed any incorrect medications. Again, I am so sorry for your loss. Please take care.

I'm very sorry for your loss, unfortunately these are general signs of a dying agonal rabbit but this does not give me any clues regarding the possible cause of death. if it happened to more than one rabbit though it's very likely to be infectious and you need to bring the rest to your vet in order to be checked and treated if needed.

I'm sorry to hear about your loss. When rabbits get sick they usually go downhill very quickly. Intestinal infection ( or dysbiosis) is a common occurrence . This usually causes a sudden loss of appetite and lethargy. Rabbits usually pass away very quickly when this happens. Of course other possibilities exist as well such as a bleeding tumor, or kidney failure. Thank you for using Pet Coach.

I am so sorry that your rabbit died. Without actually examining the rabbit it is difficult to know the cause of death but he might have had an infection or tumor that caused death. If you want to get another rabbit then you should disinfect anything the rabbit came in contact with in case it was an infectious disease. Once again, so sorry.

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.

I am sorry your rabbits are sick and passing away. I would try and locate an exotics vet somewhere around you. Even if you have to drive a little further. Unfortunately the picture and posture does not tell why they are sick. I get concerned about something contagious if you have had other rabbits die. I know it sounds sad but if a rabbit dies I would recommend taking it to the state lab for a necropsy (autopsy in people). This way they can take tissue samples and send it to the lab for hopefully a diagnosis. However we would prefer to keep the rabbits alive. Parasites like coccidia can cause death, infection, viruses, dental disease, toxins and maybe food source. The rabbits really need to have a fecal, blood work and maybe x-rays. You can try to force feed them at home with a product like critical care but they need to continue to eat or there intestines stop working which can cause fatality.
