If she’s in a bright spot, her pupils will shrink to decrease the amount of light going to her retina.

Could A Cat With Dilated Pupils Be In Pain
Cats have strong survival instincts that motivate them to hide pain as much as possible. When a cat hides the fact that it is in pain, it is not as vulnerable to predators. In many cases, a cat in pain wont vocalize much because of it.
However, the downside of the cats hiding pain is that they can suffer severe injuries from being in a fight or getting hit by a car without showing any outward signs. Dilated pupils may be the strongest indicator that your cat is injured.
Sometimes, a lasting result of an injury to the head is a condition known as anisocoria. When a cat has anisocoria, one pupil may be larger than the other. This symptom may occur years after an initial injury.

Why Are My Cats Eyes Dilated All The Time
Cats dilate their pupils to improve vision. Wide eyes allow a cat to absorb more light, which is helpful in dim lighting. Pupils also dilate when a cat is excited, afraid, or hurt. This should never last longer than a couple of hours. Prolonged pupil dilation requires further investigation. Constant dilation of the eyes is often linked to pain, overstimulation, or age-related atrophy. Your cat could also be sick. Multiple health concerns are connected to dilated pupils. The most serious of these are feline leukaemia, toxicity, dysautonomia, and tumours.
Mismatched pupil sizes in cats mean your cat has anisocoria. Sometimes, one pupil is smaller and permanently narrowed. Its more common for one eye to be permanently dilated. Your cat may keep one eye closed. Anisocoria is a symptom of another problem. Senior cats are prone to developing anisocoria.

While dogs and people can develop idiopathic anisocoria, in which the pupils are occasionally different sizes for no reason at all, this is much rarer in cats. Therefore, if you notice your cats pupils are different sizes, even occasionally, a veterinary exam is important to uncover the cause.

How Vets Diagnose The Cause Of Anisocoria In Cats
Anisocoria is a symptom that can lead to the diagnosis of an underlying disease.
When a veterinarian examines a cat with anisocoria, they will carefully inspect both eyes, checking neurologic reflexes and looking for other abnormalities that may be too subtle to notice at home or with the naked eye.
Depending on the results of the physical exam, they may recommend bloodwork, including tests for organ function or certain infections. Imaging like X-rays and ultrasounds may also be useful in achieving a diagnosis that explains the anisocoria.

Today were looking at the meaning of cats non-verbal communication: the eyes. Read on for facts about cats eyes as a way of understanding what theyre thinking.
Have you ever been innocently petting a cat when all of a sudden WAP they get you with their claws? What was that all about? You think as you dab the blood with a tissue. With their impassive faces and ability to hide pain, cats are famously hard to read, unlike dogs who are pretty transparent. Whens the last time you wondered if a dog was happy, sad or scared? Probably never.
Cats do not have expressive faces like dogs, and it all comes down to the fact that they dont have eyebrows. That makes it a lot harder to tell the meaning behind your cats eyes. Like humans, dogs use eyebrows as a communication device. Call a dogs name and up go their eyebrows. Call a cats name and they look at you as if to say, Ugh, what do you want? They arent really thinking this ; its just that their faces dont demonstrate emotion.It is theorized that cats have a small capacity for facial recognition, meaning they dont really read our expressions. So while we cant read their faces, they cant read ours, either.

Is Poisoning Responsible For Cats Pupils Being Dilated
Memphis Veterinary Specialists highlights multiple types of chemicals, plants, foods, and medications poisonous to cats.
However, dilated pupils are not a symptom in most types of poisoning. However, one notable exception is permethrin, an ingredient found in many flea and tick products. These products are designed for dogs but sometimes end up used on cats.
According to the American Association of Feline Practitioners, permethrin is a common cause of poisoning in cats.
How this poisoning happens is when people use products designed for dogs in cats. Although permethrin is a safe ingredient for dogs, it is not safe for cats. Cats often end up ingesting the ingredient during grooming.
Some of the signs of permethrin poisoning in cats include dilated pupils, excessive drooling, anxiety, muscle tremors, and seizures. Cats exhibiting these symptoms require immediate veterinary treatment to prevent life-threatening consequences.

Feline Spastic Pupil Syndrome
If your cat has anisocoria that appears to alternate between eyes, this is called feline spastic pupil syndrome. This is a symptom of the Feline Leukemia Virus .
Feline Leukemia is a serious condition and is the leading cause of death in cats after trauma. However, it is possible for cats to encounter the virus and fight it off, with 70% able to do this on their own. That being said, persistently infected felines will likely die within three years.
Because of this, if you notice your cat has feline spastic pupil syndrome then take them to the vet immediately. There is no cure for the disease, but regular check-ups and examinations can help prevent the infection from reoccurring and prevent complications.
Will My Cat Recover
The prognosis for full recovery depends upon the cause of the anisocoria. In some cases, your cat may require long-term medication to control the underlying cause. If your cat became blind as a result of the underlying disease, it is extremely unlikely that the blindness will be reversible.

Do Nutritional Deficiencies Cause Dilated Cat Eyes
According to Patricia P. Scott, cat foods with casein have been linked to Vitamin A deficiency. Pupil dilation in ordinary lighting is common in such cases.
Allivet also cites taurine deficiency as a reason for cats to have dilated pupils. Because the retina is affected, your cat may have difficulty seeing.
Taurine deficiency affects more than the eyes. Digestion issues are also typical, and the deficiency can also affect the cats heart. Pregnant females deficient in taurine may give birth to kittens with developmental or growth problems.
Your vet will be in the best position to determine whether your cat is deficient in taurine or other nutrients. Quality cat foods are usually nutritionally complete. However, your vet may direct you to use supplements for your cat.
