What Does It Mean When a Cat Has Round Pupils

The shape of a cat’s eyes can reveal their emotions and temperament. While most cats have vertical pupils, some breeds such as the Persian, Siamese, Maine Coon, Bengal, Ragdoll, Sphynx, and British Shorthair have naturally round pupils. When a cat with vertical pupils’ eyes dilate or become round, it may indicate various emotions like happiness, excitement or fear.

As your cat prepares to jump onto your lap, shoulder, or any object, you will observe that its pupils have expanded, indicating enthusiasm. This typically occurs during playtime. Your cat exhibits enlarged, circular pupils when concealing itself behind an item or possibly when feeling scared.

When a cat is displaying happiness and trust, their eyes may become dilated and wide-open. This can often be observed when they are rubbing their head against your cheek or sitting on your lap, indicating feelings of affection and trust.

Additionally, enlarged pupils may indicate a negative underlying issue. Health problems such as hypertension, kidney disease, or hyperthyroidism can also result in dilated cat pupils. It is advisable to promptly seek veterinary attention if you observe persistent dilation or any changes in your cat’s pupils.

Things To Consider

Certain breeds of cats possess naturally circular pupils. The configuration of a feline’s pupils and the placement of their eyelids are linked to their emotional state, hunting technique, and lighting conditions. They have the ability to constrict or expand their pupils in specific circumstances.

Cats can squint their eyes when they are happy or at ease. If you observe your Persian, Siamese, Maine Coon, Bengal, Ragdoll, Sphynx, or British Shorthair with narrowed pupils in your presence, it indicates that they feel secure and content. While it is normal for cats to dilate their pupils briefly, if you detect a sudden alteration in the size of their pupils or notice asymmetry between the two eyes, it is crucial to take them to a veterinarian immediately as this could be an indication of severe health issues such as infection, trauma or even cancer.
