Cat flea

A cat flea is a tiny, biting bug that likes to live on cats and other animals with fur. They are so small that you might not even see them, but you'll definitely feel them when they bite you or your pet.

These fleas can jump really far - hundreds of times their own body length - to get onto a new host. Once they're on a cat, they start biting and sucking blood for food. This can make the cat itchy and uncomfortable, and even lead to some health problems if the flea bites too much.

To get rid of these pesky bugs, there are special medications and shampoos that can kill them. It's important to treat your cat regularly to make sure they don't get infested with fleas. Other pets in the house should also be treated, and you may need to clean your home thoroughly to get rid of any flea eggs or larvae that might be hiding in carpets, bedding, or furniture.
