What Is Cat Herpes?

Cat herpes, also known as feline viral rhinotracheitis (FVR), is a highly contagious viral infection that affects cats. It is caused by the feline herpesvirus type 1 (FHV-1). Feline herpesvirus is a common respiratory pathogen in cats and is one of the primary causes of upper respiratory infections (URIs) in felines.

The virus spreads through direct contact with an infected cat, such as through sneezing, coughing, sharing food bowls or litter boxes, or grooming. It can also be transmitted through indirect contact with contaminated objects, such as bedding or toys.

Cat herpes primarily affects the respiratory system, causing symptoms such as sneezing, nasal discharge, congestion, coughing, and fever. Infected cats may also have red and watery eyes, swollen eyelids, ulcers on the eyes, and a lack of appetite. In severe cases, the virus can cause pneumonia and other complications. Supplements like lysine can help.

Once a cat is infected with feline herpesvirus, the virus can become dormant and periodically reactivate, especially during times of stress or immunosuppression. This means that infected cats can have recurrent episodes of symptoms throughout their lives.

Treatment for cat herpes focuses on managing the symptoms and supporting the cat's immune system. This may include antiviral medications, antibiotics to prevent secondary bacterial infections, eye ointments, and supportive care such as keeping the cat comfortable and well-hydrated.

Prevention of cat herpes involves minimizing exposure to infected cats and practicing good hygiene, such as regular handwashing and cleaning of shared objects. Vaccines are available to help reduce the severity and frequency of feline herpesvirus infections, but they may not prevent the virus entirely.

How Feline Herpes Affects a Cat's Eyes

Feline herpesvirus can affect a cat's eyes and cause a condition known as feline viral rhinotracheitis conjunctivitis. The virus can directly invade the conjunctiva, which is the thin tissue that lines the eyelids and covers the front part of the eye.

The most common eye-related symptoms of feline herpesvirus infection include the following.

Conjunctivitis: Inflammation of the conjunctiva leads to redness, swelling, and discharge from the eyes. The discharge may be watery or thick and pus-like. The conjunctiva may appear pink or red, and the cat may squint or show signs of discomfort.

Keratitis: Feline herpesvirus can cause inflammation of the cornea, the transparent front part of the eye. This condition is known as keratitis. It may cause the cornea to become cloudy, and in severe cases, it can lead to ulceration or erosion of the cornea. Cats with keratitis may exhibit excessive tearing, squinting, and sensitivity to light.

Corneal ulcers: The corneal ulcers can develop as a result of severe keratitis or due to direct viral damage to the cornea. These ulcers are painful and can lead to further complications if left untreated.

Blepharospasm: Feline herpesvirus infection can cause spasms or involuntary contractions of the eyelid muscles, resulting in squinting or excessive blinking.

It's important to note that feline herpesvirus eye infections can be recurrent. Stress, illness, or other factors that weaken the cat's immune system can trigger the reactivation of the virus, leading to flare-ups of symptoms.

If you suspect your cat has a feline herpesvirus eye infection, it's essential to seek veterinary care. A veterinarian can diagnose the infection based on clinical signs and may perform additional tests if needed. Treatment typically involves antiviral medications, antibiotic eye ointments to prevent secondary bacterial infections, and supportive care to relieve symptoms and promote healing.

Cat Herpes Eye Drops

The treatment of feline herpesvirus eye infections often involves the use of antiviral eye drops or ointments, along with other supportive measures. Here are a few common medications that may be prescribed by a veterinarian for treating cat herpes eye infections.

Antiviral Eye Drops/Ointments: Antiviral medications, such as topical antiviral eye drops or ointments, are often prescribed to help control the replication of the feline herpesvirus and reduce the severity and duration of symptoms. Examples of antiviral medications commonly used for feline herpesvirus eye infections include idoxuridine (IDU), cidofovir, and famciclovir.

Antibiotic Eye Drops/Ointments: Secondary bacterial infections can occur alongside feline herpesvirus eye infections, and to prevent or treat these infections, your veterinarian may prescribe antibiotic eye drops or ointments. Commonly used antibiotics include erythromycin, terramycin, or chloramphenicol.

It is important to note that specific medications and their usage should be determined by a veterinarian. Dosage and frequency of administration may vary depending on the severity of the infection and the individual cat's needs. It is crucial to follow the veterinarian's instructions carefully and complete the full course of treatment as prescribed.

In addition to medication, supportive care measures such as keeping the cat's eyes clean and free from discharge, using warm compresses to soothe the eyes, and ensuring proper hydration and nutrition are important for the overall management of feline herpesvirus eye infections. Regular follow-up visits with the veterinarian may also be necessary to monitor the cat's progress and adjust the treatment plan if needed.
