Why Do Rabbits Have Red Eyes

Rabbits have red eyes for several reasons-some good, some not so good. As a rabbit owner, you must know why your rabbit’s eyes are red. In fact, I get asked by people all the time about red eyed rabbits. So, why do rabbits have red eyes?

Which Rabbit Breeds Have Red Eyes?

Certain breeds of rabbits are naturally red eyed. These breeds often have white fur, but not always. Here’s a list of the rabbits breeds that always have red eyes:

  • Himalyan-Himalayan always have red eyes. If you think your rabbit is a Himalyan, but she doesn’t have red eyes, then she isn’t a Himalyan, but another breed of a rabbit.
  • Angora Giant-Ruby red eyes with white fur, called an Albino. Giant size.
  • Florida white-Compact size, all white fur, pink eyes
  • Lion head-Compact size, red eyes, white fur or tortoiseshell. Long wool around neck
  • Californian-Fur is white with black at the points-nose, ears, feet and tail. Eyes are red. Himalyan type markings.

The American Rabbit Breeders Associate says there are 48 different breeds of rabbits. They have varied eye colors: Blues, browns, blue-grey, pink, marbled, ruby red and flash red. The pink eyes are because of a rare mutation where a rabbit inherits two recessive genes which causes the brown eyes to have a pink look to them. We find ruby or red eyes in albino rabbits who have no pigment Albino rabbits lack melanin, which leaves them with no color in their fur and eyes. The red color in albino rabbits is the blood vessels in the eye.

Flash red is when a rabbit lacks tapetum lucidum, a layer of tissue visible in the eyes of some animals. This tissue reflects light.

A rabbit’s eye color is often similar to their fur color because they come from the same pigments-dark brown or light browns. What changes the shades of fur color is the size of melanin particles. Eyes with larger melanin particles will appear darker brown, eyes with smaller particles of melanin look blue. As rabbits get older, their eye color gets darker. This is because the size of the melanin particles increases. Because genetics plays a role in pigmentation, this tendency is more exaggerated in some rabbit breeds, but not others.

How Do I Keep  My Rabbit’s Eyes Healthy?

If your rabbit has bright eyes, normal functioning eyelids and watery looking discharge coming from her eyes, nose or mouth-it’s a good sign she is healthy. It’s also likely that her teeth are in good shape and kept trimmed with no visible abscesses.

Here are some other ways to keep your rabbit’s eyes healthy:

Good diet-The best way to keep your rabbit’s eyes healthy is to give her a healthy diet rich in grass hays, fresh vegetables, and lots of water. Your rabbits should eat her weight in hay every day to maintain a healthy digestive system as well keep her teeth trimmed down since rabbit’s teeth grow throughout their entire lives.

Dental health-Dental disease in rabbits often leads to eye illnesses so keep your rabbit’s teeth well trimmed and healthy with a high fiber diet. Too long of teeth in a rabbit can cause inflammation of the tear ducts.

Eye check-Check your rabbit’s eyes regularly for any changes. If you notice any changes,contact your vet right away so she can look at your rabbit’s eyes.

Clean cage or hutch-Keep your rabbit’s cage cleaned, remove the old straw and add fresh straw. Clean out the litter box. Remove old, stay or moldy hay from the hay rack. This will reduce bacteria from growing.

Good grooming– Rabbits are good groomers. They lick and clean other rabbit’s fur around the eyes, this helps prevent infection. If your rabbit is alone, you can keep her eyes clean by wiping them. This keeps them from getting sore.

Vet checks-Take your rabbit to your vet for check ups. Your vet can spot things early on that you might miss. Preventative care is always best for your rabbit.
