One of the most common causes of sudden rabbit death is that the rabbit was meant to live indoors and could not handle the temperatures outdoors.
Rabbits have delicate systems and a drop in temperature could kill them. It is not a good idea to keep pet store rabbits outside at all. They are indoor animals and must be kept indoors.
Deadly Fly Strike and Rabbits.
Many new rabbit owners are not aware of deadly fly strike. This happens when a germ-infested fly lands on a rabbit and lays eggs on them. The eggs hatch quickly and can literally eat a rabbit inside and out.
A rabbit with deadly fly strike gets a dirty bottom and has a foul smell. If caught early enough, treatments can save the rabbits life but their lifespan will be shorter than usual.
The best way to prevent this fatal condition is to regularly check your rabbit’s bottom and keep it clean. Use a fly guard in your rabbit’s environment and keep your them on a proper diet: no carrots, lettuce, or bread.
Rabbits Can Die of Fright
Loud sounds can scare a rabbit to the point of causing a heart attack. The rabbit may go into shock and die a few days later.
It is possible for a rabbit to die of fright. Loud sounds, such as cats, dogs, loud music, or screaming can lead to a heart attack and put a rabbit into shock, causing sudden death. It can take several days for the rabbit to die this way, and it does not happen often, but it is quite possible.
Other Animals Can Kill a Rabbit
Cats, dogs, and ferrets are hunting animals and can easily catch and kill a domestic rabbit.
Do not even consider a rabbit if you have aggressive dogs, large dogs, young untrained puppies, ferrets, or cats. Ferrets are hunters and cat are wild animals will hunt, frighten, or severely injure rabbits. Large dogs can easily induce shock and heart attacks. Puppies don’t mean to be naughty, but of course they can hurt or frighten your rabbit to death.
An Aborted Late Pregnancy Can Be Fatal
A female rabbit that aborts a pregnancy in late term may not be able to absorb the fetal tissue. The dead kits may become toxic inside her, resulting in death.
If a rabbits aborts a pregnancy and cannot reabsorb the fetus, the baby rabbits will simply die inside her and create a toxic situation. A normal miscarriage can be absorbed harmlessly, but if the pregnancy is further long when the miscarriage happens, the mother rabbit may die.
Poison Ingested Inside or Out in the Garden
Gardening products including pesticides can be fatal to a domestic rabbit. Signs of poisoning are loss of appetite and discharge from the eyes, mouth, or anus.
It is possible for a rabbit to suffer poisoning and die very quickly. They may not show any symptoms and behave normally, but if there is discharge from any area, especially the eyes, mouth, or anus, they may have eaten something poisonous in the garden. They will have very little appetite for food or water. If your rabbit dies and you suspect poison, be sure to remove the body and sterilize the area. If you have other rabbits and they seem fine, take them to the vet just in case. Possible sources of poison include gardening products, pesticides, washing powder, and other cleaning products.
Age
Once a rabbit is past three, it can be very hard to precisely identify the age. Be very careful to check a rabbit over before purchasing or adopting. Rabbits stop growing at 18-24 months of age, but read up on the breed of rabbit you are looking at so you know typical sizes for babies and adults of that type. Some rabbit sellers may pass an older rabbit as younger. Unless you are sure the rabbit is young, think twice about buying or adopting. The stress of moving to a new home might cause a very old rabbit to die sooner rather than later.
Swallowing Objects Like Glass
Before your rabbit forages in the garden, make sure to remove any sharp objects, especially pieces of broken glass or anything that could be potentially very harmful to them. Rabbits will sometimes ingest things they shouldn’t and in many cases it does them no harm. Swallowing a sharp or large object can literally tear a rabbit’s insides, causing severe internal bleeding. If you notice blood around the anus, this may be a sign of internal bleeding. If this happens, take it to the vet to have it examined immediately.
