Cat Pupils Dilate: More Than Just Light, Understanding Cat Pupil Changes and Emotions
Cat Pupils Dilate: More Than Just Light, Understanding Cat Pupil Changes and Emotions
It's no secret that cats' eyes can change size. You can observe this change within just a few days of bringing a cat home. During the day, cats have what's known as "eye balls," but in reality, it's their pupils, which can shrink to a narrow slit. As the sun sets, the pupils gradually enlarge until they become large, round, and black at night.
As the sun rises, the pupils return to their narrow slit shape. While this may seem odd to some, it's quite normal for cat owners. The reason for this change in pupil size is to regulate light, preventing too much light from hurting their eyes and allowing them to see better in dim lighting.
Cats are nocturnal animals. At night, their eyes become large and round, and the cat itself seems more alert. It's a great time to take photos of your cat, particularly close-ups of their eyes, which can be stunning. Just remember to turn off the flash, as the sudden bright light can damage their eyes when their pupils are dilated.
However, a video went viral recently showing a cat whose pupils dilated upon seeing its owner. This led many owners to try the same experiment. Naturally, I couldn't resist.
Unfortunately, my results weren't as clear. While my cat's eyes didn't immediately widen upon seeing me, her pupils did dilate quickly when she saw my finger, followed by a bite, as if she was playing.
This led me to further observe her, and I discovered that her pupils would dilate when she saw a toy, particularly the feather on a toy wand, and she would immediately attack it. So, it's true that cats' pupils can dilate when they see someone they like. And it seems that people hold the same level of importance as their favorite treats and toys.
This observation also suggests that cats can adjust their pupils independently of light. Consider how your cat's eyes are usually narrowed during the day, even when not directly looking at the sun. Their eyes are often half-closed, even when looking up. If the cat is happy, it might appear sleepy. If they're unhappy, they'll often look like they don't want to be bothered.
Yet, at night, with the lights on, your cat's eyes are usually round and not narrowed like during the day. This phenomenon isn't limited to cats. Humans, too, unconsciously dilate their pupils when they see people or things they like. It's said that in ancient times, Persian merchants would use the degree of pupil dilation when someone looked at a jewel to determine its price.
Cat Pupil Changes: From Light to Emotions
Cat pupils are affected not only by light but also by their emotions. When a cat feels excited, agitated, nervous, or scared, their adrenaline levels rise, causing their pupils to dilate. When the cat calms down, their pupils return to normal.
When playing with toys, a cat can get excited, feeling the thrill of the hunt, causing their pupils to dilate. This helps them see more detail. If you're holding your cat in a strange environment, their pupils might remain dilated because they're feeling nervous or afraid.
As for why my beloved cat didn't show this pupil dilation, it's likely because she's used to me. It's like a favorite ring you wear every day – it's no longer as exciting as the first time you saw it.
When you see videos of cats' pupils dilating and try it with your own cat, they might be wondering what you're doing.
So, next time you haven't seen your cat in a couple of days, try walking up to them unexpectedly and see if their eyes widen!
Beware of Continuously Dilated Pupils
Large, round pupils are attractive, but if your cat's pupils stay dilated all the time, even without light stimulation, or if their eyes are always narrowed, it's time to visit the vet. If your cat's pupils are constantly dilated, they might be suffering from chronic kidney disease, hypothyroidism, or eye diseases like cataracts. In such cases, it's crucial to take your cat to the vet as soon as possible.
Let's hope your cat greets you with wide, welcoming eyes when you come home!
Summary:
Cat pupil dilation isn't just about light adjustment; it's also a barometer for their emotions. By observing their pupils, we can better understand their inner world and catch potential health issues early. Next time you're observing your cat, pay attention to their pupil changes – you might discover some intriguing secrets!
