Are Some Cat Breeds More Likely To Have Watery Eyes

Conversation feline eye herpes

Both conjunctivitis and congenital allergies can impact cats of any age, sex, or breed.

Bacterial infections that can cause conjunctivitis are transmitted in a variety of ways. For instance, bacteria can be passed between cats in a multi-cat household or between outdoor cats. But even if your cat is an only child who lives for the comforts of indoor life, theyre still susceptible to bacteria if they interact with contaminated items, like that dirty shoe they keep attacking. Bacteria doesnt discriminate, so if a cat is exposed, they can contract a bacterial infection regardless of their breed.

The leading cause of conjunctivitis, Feline Herpes Virus, is also common, and every breed is susceptible. In fact, over 90% of cats live with FHV.4

Similarly, any cat, regardless of breed, can be born with a congenital allergy.

Is Feline Herpes Contagious

Feline herpes is contagious. The virus spreads through respiratory fluids such as saliva and discharge from the nose or eyes, including when a cat sneezes.

Herpes can spread through direct contact or indirectly. The most common cause of indirect contact is peoplewhen a person pets a sick cat, then pets a healthy cat. Indirect spread also occurs when objects are contaminated with the virus. If a sick cat eats out of a food bowl, and then a healthy cat eats out of the same food bowl, the healthy cat could get herpesvirus.

Feline herpes is very specific to cats. Cats cannot give it to humans, to dogs, or to any other species of animal.

Diagnosing Feline Herpes Virus

Although it’s one of the most common causes of upper respiratory disease in cats, feline herpes virus isn’t the only thing that can cause upper respiratory signs in your cat. There are subtle differences, though, and you vet will hone in on a diagnosis of feline herpes virus based on your cat’s symptoms, history, and physical exam.

Your vet may perform a test called a fluorescein stain to check for a corneal ulcer caused by severe keratitis. They may also perform a Schirmer tear test to see if your cat’s tear production is abnormally low.

If you want a definitive diagnosis of feline herpes virus, your vet will need to take swabs of your cat’s ocular discharge, nasal discharge, and/or of the back of their throat. These swabs will be sent to a lab where they will undergo a specialized test called a Polymerase Chain Reaction . This test allows the viral particles to be amplified and thus isolated and identified. However, if your cat isn’t in an active stage of infection, there won’t be any viral particles being shed and this PCR test will be inconclusive.

Medication For Feline Herpes

When cats are not very active, are very congested, or have a lot of yellow-green discharge from the eyes or nose, your veterinarian may prescribe antibiotics. This will eliminate any secondary bacterial infections. Antibiotics will also often shorten the course of disease.

Depending on your cats symptoms, your veterinarian may prescribe either antibiotics by mouth or into the eye. The best choice of antibiotics by mouth for an upper respiratory infection include doxycycline and azithromycin. Some choices of antibiotics in the eyes include erythromycin, Terramycin, tobramycin, or ofloxacin.

While antibiotics may help shorten the length of time your kitty is feeling ill, they will not treat the virus itself. A very common antiviral medication taken by mouth in cats to kill herpesvirus is called famciclovir. It has limited side effects and is most often used when cats have one of the more uncommon conditions, such as keratitis, stomatitis or dermatitis. It may also be used when cats have chronic symptoms related to herpes such as chronic congestion or eye infection.

Features To Consider When Buying Cat Eye Drops

One product that cat owners should have on hand is a bottle or two of eye drops for their cats, especially if their furry friends frequently experience allergies or conditions that directly affect their eyes.

Cats that wander in and out of the house may occasionally get some irritants like dirt and dust in their eyes. Hence, even perfectly healthy cats would greatly benefit if their fur parents have readily available eye drops at home.

Since this type of medication often addresses symptoms and is not directly used for a full treatment of any ailment, they are safe to use daily. When buying, find a medication with these features to ensure that you get the best product for your furry friends:

Safe Ingredients. Examine the ingredients list and make sure that the eye drops you’re getting are entirely safe to use even without a prescription from a veterinarian. One example of a safe ingredient is hypochlorous acid, a safe antimicrobial agent. Bear in mind that the use of incorrect medication may result in further irritation which we do not want to happen. If you find products that contain alcohol or bleaching agent, it’s best to avoid them.

Application.Find a product that is easy to apply. Some drops may come with droppers, which make it a lot easier for cat owners to administer the application of eye drops on their fur babies.

Nursing A Cat With Feline Herpes Virus

Home nursing of the cat with FVR is make or break. Usually these cats feel lousy and have lost their sense of smell, which means they lose their appetite and hitch a ride on a downward spiral of deterioration.

Whilst there is not drug proven to kill herpes virus the vet may prescribe antibiotics against secondary bacterial infections and to protect the cat at risk of pneumonia. In addition, ask your vet if decongestants are appropriate. Usually this is a powder you mix with food that helps to break down mucus and snot. This makes it easier for you to keep kittys nose clean, which helps her smell food and eat.

Keep her nose as clean as possible, and wipe her eyes with cotton balls soaked in boiled water, as often as needed to prevent the eyes gumming shut. To help her appetite chose smelly foods such as fish, and warm it up so that it gives off even more odour. Hand feeding usually goes down a storm as cats love the attention, and also try touching food to her gums so she gets the taste in her mouth.

Stress suppresses the immune system which allows the herpes virus to get a hold, so keep stress to a minimum and consider using synthetic feline pheromones such as Feliway to keep the cats chilled.

Clinical Manifestations Of Disease

Purulent nasal and ocular discharge can be present with viral infection alone, however, secondary bacterial infection is common. Most commonly, primary infection is self-limiting meaning the kittens immune system is able to clear the disease within 10-14 days. However, the course of the disease can be extremely variable. In adult cats or cats with recurrent infection, clinical signs are typically less severe and only involve the eyes.

Conjunctivitis is the most common disease caused by FHV-1 and is the most common feline ophthalmic disease. Most cats with conjunctivitis are blepharospastic with ocular discharge, conjunctival hyperemia and chemosis . Clinical signs can range from mild to severe and ocular discharge can range from serous/epiphora to mucoid to purulent. Cats with ulcerative conjunctivitis tend to be more painful. In young kittens, ulcerated conjunctiva can heal to itself or to corneal ulcers, forming symblepharon which can lead to severe permanent visual deficits. Chronic conjunctivitis can also lead to scarring of the palpebral conjunctiva and entropion.

Treatments For Your Cats Watering Eyes

If your vet determines that your cats eyes are watering due to bacteria-induced conjunctivitis, theyll also prescribe an antibiotic to eradicate the bacteria. In the case of the Feline Herpes Virus, your vet is unlikely to prescribe an antibiotic, since they cant eradicate viruses.

Regardless of whether your cats watering eyes are due to a bacterial or viral infection, you can supplement your cats eye recovery with Vetericyn Plus Antimicrobial Eye Wash. Our non-stinging formula gently cleans your cats eyes, restores natural moisture, and helps prevent future irritations.

For cats with congenital allergies, your vet will likely prescribe eye drops and recommend making changes to your cats environment.

  • If your cats eyes are watering and theyre also scratching themselves or rubbing up against objects to itch themselves, they could be experiencing an allergic reaction.

If you notice any of the symptoms above, in addition to your cats eyes watering schedule an appointment with your vet. Before your appointment, document all symptoms to the best of your ability.

What Is The Feline Herpes Virus

FHV is an upper respiratory virus of cats. It is very common among cats, especially in environments with multiple cats. The virus most commonly infect kittens, where it replicates in the upper respiratory tract and the conjunctiva of the eyes. Nasal and ocular discharge and sneezing are the most common signs noted. Vaccinated cats may still develop the disease, although the illness is usually less severe. In very young cats adhesions of the conjunctiva to other areas of the eye may occur.

Complications Of Cat Eye Herpes

Repeated outbreaks of ocular herpes can cause scarring of the cornea and degeneration of the cornea that can lead to vision loss. Although more than 90 percent of cats are infected with FHV-1, most remain carriers. Cats with weakened immune systems, kittens and older pets are likely to have outbreaks of the infection. Kittens may also succumb to this infection if its left untreated. The virus is not contagious to humans.

Supplements added to your pets diet such as L-lysine, an amino acid, have been proven to limit the life cycle of the herpes virus and limit outbreaks of the infection. A stress free environment can also help prevent outbreaks.

Prevention Of Feline Ocular Herpes

Vaccinating your kitten for feline herpes is your first line of defense. With the feline herpes virus being so common, its imperative to vaccinate the kitten on schedule. The vaccination is not 100% effective in preventing infection, but in addition to the protection from initial infection, vaccinated cats are less likely to develop a major disease. Boosters for this vaccine may be needed later on during the cats lifetime. Consult with your vet regarding the best vaccination schedule for your cat, as this may depend on the cats overall health and living conditions.Many owners of herpes kitties still choose to supplement their cats diet with the amino acid L-lysine. Unfortunately, recent studies show that this isnt effective against the feline herpes virus.

Even if you choose to use l-lysine, please remember that no supplementation can replace topical anti-viral medication in the case of active ocular herpes infection. Forgoing proper medical treatment for this condition could make your cat blind, so please follow the vets orders and take good care of your cats eyes!
