A cat with a dilated pupil can seem mysterious and unpredictable. But did you know that there are several reasons for this behavior?
One of the most common questions cat owners have is why their cat’s pupils are dilated. Although it may seem worrying, it’s not always a warning sign.
In this article, we’ll find out about the causes and possible solutions for dilated pupils in cats, and when it’s necessary to seek veterinary help.
What are dilated pupils?
The pupils are the black parts in the center of the eyes. They are responsible for regulating the amount of light entering the eyes and act as a kind of adjustable lens.
When the pupils are dilated, it means that they are more open than normal. This can be caused by a number of factors, including changes in the environment or health problems.
Causes of Dilated Pupils in Cats
Cats’ eyes have three pupil shapes: vertical, elliptical and round. Normally, cats’ pupils are vertical, but when there is a lot of light in a space, they become ellipse-shaped, and if the space is dark, the pupils dilate and become round, allowing more light in.
Dilated pupils can occur for a variety of reasons, some of which are perfectly normal.
Most of the time cats have dilated pupils due to their hunting instinct, but it also happens that when a cat is in a dark room or feels threatened, its pupils dilate to allow more light in, giving them better vision and allowing them to have excellent night vision to protect themselves from a possible attack by predators.
In addition, cats have a membrane behind their eyes, known as the tibetanus lucidum, which absorbs and reflects light back to the retina, allowing them to see well in the dark.
When the pupils dilate, it can also indicate that the cat is feeling emotions such as excitement, stress, anxiety, fear or satisfaction. In addition, pupil dilation can also be a sign that something is wrong with your cat’s health.
If they remain dilated for a long period of time, this may indicate the presence of a more hidden problem.
Common causes of dilated pupils in cats include:
Excitement: when a cat is very excited or nervous, on a very hot day for example, it is normal for its pupils to be round or ellipse-shaped.
Fear: if a cat’s pupils are dilated and its eyes are wide open, it may be afraid of something, such as a loud noise, the presence of a stranger or another cat.
Stress and anxiety: pupil dilation can be a natural response of the cat’s body to these feelings. In other words, when a cat is stressed or anxious, its pupils may be more dilated than normal.
Satisfaction: in situations that produce happiness, cats’ pupils usually dilate as a reflex, for example after eating.
Pain or discomfort: there are various medical conditions that can cause pain or discomfort in a cat and consequently result in the dilation of its pupils. This can include dental infections, chronic diseases such as arthritis and even physical injuries.
Side effects of medication: certain medications can have side effects that include dilated pupils in cats. This can include drugs to treat pain, anxiety or other conditions.
Neurological disorders: some neurological conditions, such as brain tumors, can affect a cat’s nervous system and lead to dilated pupils.
Eye infections: eye infections such as uveitis or conjunctivitis can cause pupil dilation in cats.
Toxicity: some substances that are toxic to cats, such as plants or household chemicals, can cause dilated pupils as a symptom.
Symptoms of dilated pupils in cats
In addition to dilated pupils, there are other symptoms that may indicate that your cat is experiencing a health problem. Some of these symptoms include:
- Difficulty seeing
- Red or watery eyes
- Agitated or strange behavior
- Sensitivity to light
If you notice any of these symptoms in your cat, it’s important to take him to the vet immediately.
What should I do if my cat has dilated pupils?
If this happens, but the environment has normal light and the cat is not stressed or experiencing any other stimuli that would justify the dilation, it is important to take your pet to the vet.
Dilated pupils can indicate a number of conditions, so it is essential that a professional assess the cat and determine the cause of the dilated pupils.
In addition, it is important to observe other unusual symptoms or behaviors that the cat may be showing, such as lack of appetite , vomiting, changes in urine or stool, lack of energy, agitation or lethargy.
These symptoms can help the vet better understand the problem and define the best treatment for your cat.
Cat with dilated pupils
If you notice that your cat’s pupils remain dilated for a prolonged period of time, or if they show any of the above symptoms, it is crucial to seek veterinary attention.
Your vet can diagnose the underlying cause of your cat’s dilated pupils and recommend the appropriate treatment. If your cat has ingested a toxic substance, immediate medical attention may be required.
Treatment options
Treatment for dilated pupils in cats will depend on the underlying cause. If your cat’s dilated pupils are due to the side effects of medication or a minor eye infection, your vet may recommend eye drops or other medication to relieve the symptoms.
In more serious cases, surgery may be necessary.
Conclusion
Dilated pupils can be a sign of a normal condition or something you should be more aware of. That’s why it’s essential to pay attention to your cat’s behavior and seek veterinary care if necessary. Provide your cat with a safe and toxic-free environment.
And remember, if you notice that your cat’s pupils remain dilated for a prolonged period or if it exhibits other symptoms such as rapid breathing, agitation or weakness, seek veterinary attention immediately to ensure your pet’s health and well-being.
