Why Would My Cat Have One Eye Totally Dilated And One Not

A cat's eyes being dilated can be a sign of illness elsewhere in their bodies. If you have a cat with one dilated and one is not, there are a number of things that could be wrong. There are a number of over the counter medications that you can try but if they do not do the trick you may need to take your cat to the veterinarian, it may be an indicator of other problems.

Cats can develop a number of eye problems such as cat herpes and cat glaucoma as well as cat leukemia and feline immunodeficiency disease. If your cat is developing problems such as these there are a number of over the counter cat eye drops that can relieve most common eye problems cat s experience. The problem can either be viral or bacterial based, so check the instructions on any medication you buy to make sure you know what you are buying.

There are many different diseases that can affect your cats eyes and therefore its health. Since cats are just like us and only have one set of eyes to work with, it is imperative that you monitor this part of your cat's health very carefully. If over the counter medication does not clear the problem up within a couple of weeks, you need to seriously consider taking your cat to your local veterinarian. Since a problem with a cat's eyes can indicate a general health problem, it could very well be an alert that there is something seriously wrong with your pet.

If you take care of your pet cat like you would a family member, and they are indeed a part of your family, they will be around to give you years of love and enjoyment and they'll be happier too when they feel healthy and happy.

This is called anisocoria--when the pupils are different sizes.  It can be caused by neurological problems, trauma, Horner's syndrome, and primary ocular diseases.  Your cat needs to be examined by a veterinarian to determine the cause and start treatment if appropriate.  Not all causes of anisocoria are benign.

This is either a blind eye, or your cat has a head injury. This should not be ignored, take the cat to a vet.

It could be blind in one eye. There is no reason to get rid of it, I have a cat who is totally blind, but she can see shadows. Her eyes also do not dilate at all, and they look kinda creepy that's why she weird most people out. She looks like she's staring through you, Lol. ^_^

My cat has that too

Your cat had a stroke, also known as cerebral vascular accident

My cat developed a dilated pupil also. Her mouth droops on the same side of the dilated pupil. She also has a tumor or cancer in her lower mandible on the same side. I think the tumor or cancer came first. It is getting larger. Has difficult time eating but still meows and walks around and purrs and talks to me. Poor baby. My sister and dad said dilated pupil is a stroke. She is old.
