When Do Russian Blue Cats Eyes Turn Green: Common Eye Failure of Russian Blue Cats

When a Russian Blue kitten is born, its eyes are usually blue or grey. As the kitten grows and develops, its eyes will change color. The eyes will gradually transition from blue or grey to green, usually around 4 to 6 months of age. The exact timing of the color change can vary from cat to cat. Some Russian Blue cats may have green eyes as early as four months, while others may not have fully green eyes until they are a year old or more.

Common Eye Failure of Russian Blue Cats


Conjunctivitis, or “pink eye,” is a common eye condition affecting cats, including Russian Blue cats. It is an inflammation of the conjunctiva, the thin, transparent membrane that lines the inside of the eyelid and covers the white part of the eye.

Various factors, including bacterial, viral, or fungal infections, allergies, irritants, and other underlying health conditions, can cause conjunctivitis. Some common symptoms of conjunctivitis in cats include redness and swelling of the eye, discharge or tearing from the eye, squinting or blinking, sensitivity to light, crusts or debris around the eye, and rubbing or pawing at the eye.

Treatment for conjunctivitis depends on the underlying cause of the condition. In many cases, antibiotic eye drops or ointments may be prescribed to help clear up the infection. Anti-inflammatory medications may also be used to reduce swelling and discomfort. In addition, it’s important to keep the eye clean and free of discharge by wiping away any discharge with a clean, damp cloth.

Eye Infections

Eye infections are a common problem in cats, including Russian Blue cats. Infections, including bacterial, viral, or fungal, can affect the eyes. Some common symptoms of an eye infection in cats may include redness and inflammation of the eye, watery or thick discharge from the eye, swelling around the eye or eyelids, squinting or closing the eye, rubbing or pawing at the eye, and sensitivity to light.

If you suspect that your Russian Blue cat has an eye infection, it’s important to seek veterinary care. Your vet will examine your cat’s eyes and may take samples for culture or perform other diagnostic tests to determine the underlying cause of the infection.

Treatment for an eye infection will depend on the type of infection and severity of the condition. Bacterial infections can usually be treated with antibiotic eye drops or ointments, while viral or fungal infections may require different medications. In addition, your vet may also prescribe pain or anti-inflammatory medication to help reduce swelling and discomfort.

Corneal Ulcers

Corneal ulcers, including Russian Blue cats, are eye injuries that can affect cats. Corneal ulcers occur when the cornea’s surface, which is the clear outer layer of the eye, becomes damaged or eroded. This can happen due to various causes, including trauma, infections, irritant exposure, or underlying medical conditions.

Treatment for corneal ulcers may involve topical or oral antibiotics to help prevent infection and medications from helping reduce inflammation and promote healing. Your vet may also recommend keeping your cat’s activity level low to help prevent further damage to the eye.


Glaucoma is a condition that can affect cats, including Russian Blue cats. According to PetPlan, it occurs when there is an increase in pressure within the eye, which can damage the optic nerve and lead to vision loss. Glaucoma is a serious condition that requires prompt treatment to prevent further damage to the eye.

If you suspect your Russian Blue cat has glaucoma, it’s important to seek veterinary care immediately. Your vet will perform a thorough eye examination and may use imaging tests to measure the pressure within the eye.

Treatment for glaucoma may involve medications to help reduce the pressure within the eye, such as topical or oral medications that lower intraocular pressure. In some cases, surgical intervention may be necessary to help drain excess fluid from the eye and relieve pressure.

To prevent glaucoma in your Russian Blue cat, it’s important to schedule regular veterinary check-ups to monitor their eye health. Some cats may be predisposed to glaucoma due to genetic factors, so it’s important to be aware of potential risks and work with your vet to manage the condition. Also, managing any underlying health conditions that may contribute to glaucoma, such as high blood pressure, can help reduce the risk of developing the condition.

Progressive Retinal Atrophy

Progressive retinal atrophy (PRA) is a genetic eye disorder that can affect cats, including Russian Blue cats. It is a degenerative condition that affects the photoreceptor cells in the retina, which can lead to vision loss and blindness over time. A mutation causes PRA in one or more genes that control the development and function of the retina.

If you suspect your Russian Blue cat has PRA, seeking veterinary care for an accurate diagnosis is important. In addition, your vet may perform an ophthalmic examination, including a thorough evaluation of the retina and other structures of the eye, to determine the extent of the damage.

Unfortunately, there is no cure for PRA, and treatment is largely supportive. Therefore, your vet may recommend strategies to help your cat adapt to their vision loss, such as changing their environment to reduce hazards and improve their quality of life.

To prevent PRA in your Russian Blue cat, working with a reputable breeder who can provide health certifications for both parents and has screened them for genetic disorders is important. Genetic testing can also help identify carriers of the gene mutation that causes PRA, allowing breeders to make informed breeding decisions to reduce the risk of passing the mutation to future generations.
