Albino rabbits

Albino rabbits have white fur and red or pink eyes due to a genetic mutation that prevents the production of melanin, the pigment that gives color to skin, fur, and eyes. Albinism is caused by a recessive gene, meaning a rabbit must inherit two copies of the gene, one from each parent, to be albino.

The lack of melanin in the iris, the colored part of the eye, results in the red/pink eye color. The iris has pigment that determines eye color. In albino rabbits, there is no pigment present. Light enters the eye, reflects off the back of the eye (the retina), and then reflects back out through the iris, resulting in the red/pink eyeshine. The retina contains blood vessels which give it a pinkish hue. This color is reflected out through the iris, causing red/pink eyes.

Albino rabbits have normal vision, though they may be more light sensitive due to the lack of pigment in the iris. The iris helps regulate light levels entering the eye. Without melanin, albino rabbits have less natural protection from UV light exposure. Their light pink/red eyes are also more vulnerable to damage and require diligent care.

Providing albino rabbits with proper housing is essential. They should be kept indoors and their enclosures placed away from direct sunlight. Albino rabbits may benefit from housing with subdued lighting. Sunglasses designed for rabbits can shield their sensitive eyes from harsh outdoor light.

Daily ophthalmic exams check for signs of injury, infection, or irritation. Signs include redness, swelling, squinting, crusty or runny discharge, and excess tearing. Albino rabbits are prone to eye issues and early veterinary care can prevent complications.

With attentive care, albino rabbits can live long, healthy lives and make wonderful pets. Their distinctive white coats and pink eyes give them a beautiful and unique appearance. While they require diligent solar protection and eye care, albino rabbits can thrive in a caring home.

Do rabbits with red eyes need special care?

Rabbits with red eyes do not necessarily require special care simply due to their eye color. However, red eyes can be an indication of albinism or other conditions that do warrant particular attention regarding their health, especially eye health.

Albino rabbits with red eyes are deficient in pigment and thus more vulnerable to sun damage, eye injuries, and vision problems. They require protected housing away from direct sunlight. Their red eyes are sensitive and prone to irritation, ulcers, and infection if not tended to daily. Sunglasses, eye drops, ointments, and medications may be needed to manage eye issues.

Similarly, some rabbit breeds prone to albinism like Himalayans may need their red eyes cared for diligently to prevent problems. Breeds with eye colors other than red are not as high risk. Checker giants and chinchilla rabbits, for example, occasionally have ruby red eyes alongside dark fur. These rabbits do not require special eye care simply for their red iris color.

However, if a rabbit has red, swollen, crusty, weepy, or squinted eyes, they need veterinary attention. Red eyes accompanied by these symptoms signal eye infection or injury. Left untreated, even minor issues can worsen. Ophthalmic antibiotics, anti-inflammatories, and other medications may be prescribed to treat rabbit eye conditions.

In rare cases, red eyes in rabbits result from a more serious health problem like glaucoma, cancer, or high blood pressure. Veterinary assessment determines if red eyes indicate an underlying condition requiring extensive treatment. Never ignore changes to your rabbit’s eyes. Redness, swelling, discharge, squinting, or watering need prompt medical care.

While red eyes alone are not cause for alarm, they can sometimes indicate health vulnerabilities requiring attentive care. Know your rabbit’s specific needs based on breed, albinism risk, and watch closely for any eye changes needing veterinary consultation. Visit your exotics vet annually to identify eye issues early.

Albinism is a recessive trait

Albinism, the genetic condition that causes animals to have white fur and red/pink eyes, is caused by a recessive gene. This means two copies of the gene, one inherited from each parent, are required for an animal to be albino. If an animal inherits only one copy, it won't be albino but will be a carrier who can pass the gene on.

In rabbits, the gene for normal pigment is denoted as “C” while the albinism gene is “c”. Rabbits can have two copies of the normal pigment gene (“CC”), one of each (“Cc”), or two albino genes (“cc”). Only those with the “cc” genotype express albinism.

When two carrier rabbits with the “Cc” genotype breed, there is a 25% chance of albino “cc” offspring in each litter. Carriers don't exhibit albino traits but can produce albino babies if paired with another carrier. Identifying carrier status through genetic testing can prevent surprise albino litters.

Some rabbit breeds like Himalayans, Californians, Thrianta, and others are predisposed to albinism due to selective breeding perpetuating the recessive gene. Crossing two recessive red-eyed rabbits almost guarantees albino babies. Responsible breeding minimizes this risk by carefully choosing pairings less likely to inherit two recessive genes.

No cure exists for albinism in rabbits, it is managed through diligent care and protection from sun damage. Albino rabbits should not be bred, as albinism carries health vulnerabilities. While cute, purposefully breeding for albino rabbits propagates a challenging hereditary condition.

Understanding how albinism is passed down genetically helps rabbit owners and breeders reduce its incidence through wise pairing choices. Identifying carrier status allows preventing unintentional albino litters. With careful breeding management, this recessive trait can become increasingly rare in domestic rabbit populations.

Which rabbit breeds have red eyes?

Always have red eyes:

  • Himalayan – This breed has white fur with color on the ears, nose, feet and tail. Red eyes are due to the Himalayan gene which causes albinism of the body.

  • Albino – Albino rabbits of any breed have red eyes due to total lack of melanin. Often found in breeds prone to albinism like Himalayans.

  • New Zealand White – An all-white rabbit originally bred for laboratory use.Have red eyes due to selective breeding of albinos.

  • Californian – An albino variant of the breed, with red eyes and pink nose. Regular Californians have dark eyes.

  • Thrianta – A new breed developed from Himalayans to have albino features and red eyes.

  • Swiss Fox – White rabbit breed with red eyes derived from albino strains.

Sometimes have red eyes:

  • Checkered Giant – Normally have brown eyes but ruby-eyed variant exists.

  • Chinchilla – Standard eye color is brown but red eyes are allowed per breed guidelines.

  • Cinnamon – Usually brown eyes but red eyes occur in albinos.

  • New Zealand – Though this breed typically has brown eyes, albino strains exist with red eyes.

  • English Angora – Normally blue-eyed but red-eyed albinos sometimes occur.

  • Dutch – While blue-eyed is preferred, some bloodlines carry ruby-eyed genes.

Other common rabbit eye colors

While red eyes in rabbits often indicate albinism, many breeds exhibit other natural eye colors:

Brown – The most common eye color, seen in wild rabbits and breeds like the Netherland Dwarf. Ranges from light chocolate to dark brown.

Blue – A striking light blue eye color found in breeds such as the Vienna Blue.

Gray – A darker slate gray eye color often seen in Chinchilla rabbits.

Amber – A warm golden/orange eye color exhibited by breeds like the Cinnamon.

Green – A rare, vivid green eye color sometimes occurring in Silver Fox rabbits.

Odd/Split – Two different eye colors, like one blue and one brown. Seen in breeds like English Spots.

Pink – Very light red/pink eyes are typical of albino rabbits due to lack of melanin.

Many breeds allow multiple eye colors. Check breed standards for preferred and permitted eye colors. While red often indicates albinism, diversity exists even within red shades, ranging from ruby to deep burgundy. Eye color genetics in rabbits is complex and still not fully understood.

Red eye infection in rabbits

While red eyes in rabbits can be completely normal, sometimes red, swollen, irritated eyes indicate an eye infection requiring veterinary treatment. Common causes of red eye in rabbits include:

Conjunctivitis – Inflammation of the conjunctiva, the pink tissue lining the eyelids. Caused by irritants, allergies, or eye infections.

Blepharitis – Swelling of the eyelid margins, also causing crusty buildup.

Ulcer – Painful open sore on the cornea, often resulting from injury.

Foreign Object – Debris trapped under eyelid, such as bedding material.

Glaucoma – Increased eye pressure causing bulging, red eyes.

Dental Issues – Misaligned or overgrown teeth irritating the eyes.

If your rabbit's eyes appear red, swollen, runny, crusty, teary, or squinted, contact your exotic vet for an urgent appointment. Leaving eye infections untreated can lead to blindness, loss of the eye, and even systemic illness if bacteria spreads.

Your vet will examine the eyes with magnification and specialized lighting to determine the cause. Treatment may include antibiotic and anti-inflammatory eye drops/ointments, pain medication, and even surgery if a foreign object or ulcer is present.

Follow your vet's instructions carefully regarding medication dosage and frequency. Finish the full course as directed, even if symptoms improve beforehand. Seek immediate followup if symptoms worsen or do not start improving within 2-3 days.

Red eyes in rabbits should never be ignored, as what looks like minor irritation could be something more serious like a corneal ulcer or glaucoma attack. Catching problems early maximizes chances of successful treatment and preventing permanent damage. Monitor your rabbit's eyes daily and contact your vet at any sign of redness, irritation, or discomfort. With prompt care, most common eye infections in rabbits resolve fully.
