December 27, 2018

Cat eye infection is relatively common among cats. As a cat owner, you should not underestimate the severity of feline eye infections. In extreme cases, your pet cat may go blind as a result of delayed treatment. As such, if you suspect your cat of having an eye infection, it is best to bring it to the vet.

Causes of Cat Eye Infection

Feline eye infections are caused by a number of bacteria, fungus, parasites and viruses. Some infections like bacterial eye infections are secondary conditions caused by injuries or viral infections. An eye infection may be the onset of a more serious underlying medical problem.

Viral eye infection
The feline herpes virus and to a lesser extend the feline calicivirus are the most common types of viral eye infections. The feline herpes virus is responsible for most of the eye infections such as conjunctivitis brought about in viral infections. Once a cat is infected with this virus, the infection will be lifelong as the virus cannot be totally eradicated from the body. Flare-ups will occur if the cat is under stress.

A good immune system is required to suppress the feline herpes virus as this condition is stress induced. As such, it is important to provide a healthy diet and enough exercise and rest for your cat to ensure its immune system is functioning well.

Many times, cat owners misjudge what is stressful or not stressful for their pets. This is something you need to take note of as certain situations you find alright, may be in fact stressful for your pet. For example, if there is a new addition to the family in the form of a newborn baby, the crying may be too much for your cat to handle, leading to a flare up again.

Bacterial eye infection
