Cats are the second most popular pets in the world.

You know that they are cute and seemingly cuddly (only when they want to be), but I bet you didn’t know about these interesting cat facts.

facts about cat - here are some interesting tidbits about the biggest star of the internet

Below are 7 interesting and fun facts about cats you might not know.

1. Fact about Cat and Seawater

Drinking seawater dehydrates the human body, but did you know that cat’s unique biology allows them to process seawater?

Now, this is something that not every living creature on Earth can do. As a human, we know that it’s not safe for us to drink sea water. Seawater contains too much sodium content. When consumed directly without prior filtration, it dehydrates our body. But if you have a cat and you’re near the beach, you can absolutely let them go wild with the salty ocean water. We doubt that they’d want to go that way though since cats aren’t too keen on being in the water — but you already know that.

2. Fact about Cat and Chocolate

Absolutely do not feed a cat any chocolate, because they are toxic to cats. But even if you do share chocolate with them, these feline creatures will not be able to taste it.

Can you imagine not being able to eat anything sweet? Well, no wonder why cats are so grumpy most of the time! This is actually caused by a mutation in their taste receptors. So if you’re thinking of giving them sweets as a treat, they might as well skip it because they’re not going to feel rewarded after all. As a matter of fact, DO NOT even try to even feed them chocolate because chocolate is toxic for cats.

3. Fact about Cat Ears

For one, cat ears have furry tuffs on the inside. A true cat owner will know how hard it is to clean up their ears just because they’re so deep! But their ears’ structure actually filters out the debris and prevents their ears from receiving sounds directly. Although you can think of their ears as “sound-proofed”, their hearing can be quite extensive. They can hear ultrasonic noises that some bats, rodents, and dolphins make! This is how they communicate with other cats and animals that could produce the same wavelength.

4. Fact about Cat Nose

Now that we’re on to cat’s facial structures, did you know that every cat’s nose is unique?

It’s true that almost all cats look the same and if you’re just a normal person who looks at them, you won’t even see the difference between each one. But there is a difference! If for us, humans, our fingerprint is unique to each one of us and helps identify a person, cat’s noses are unique to an individual, too! It seems like they don’t look like each other after all.

The action is called kneading, and it is associated when cats are still kittens and are about to drink milk from their mother’s breasts.
