Why do cats keep licking their paws?
Cats often use their mouths to clean their paws, a behavior that may seem amusing, but there are actually many reasons behind it. The following will explain in detail the reasons and significance of cats cleaning their paws.
1. Keep paws clean and hygienic.
A cat's paws get dirty easily and can harbor germs and bacteria. This is one of the reasons why cats constantly clean themselves. Cats use their legs and tongues to clean their paws, especially the crevices between their toes and their nails. The way cats use their tongues helps remove dust and dirt from their paws, keeping them hygienic and clean.
In addition, they will use their tongues to scratch their claws when they are stimulated, such as by dust and stones on the road. 
2. Claws help promote digestion.
If your cat frequently scratches its paws (especially after eating), this is likely a normal bodily response. Licking can also help with digestion.
A cat's tongue has a thin layer of mucus containing enzymes that promote digestion. Many felines like to lick their fur after eating, and the enzymes on their tongues coat the fur in their mouths, making it easier to digest the hair that is swallowed into their stomachs.
It is also mentioned here that cats will drool on their paws before wiping their fur to help them digest better.
3. Claws can be a sign of physical discomfort.
Cats licking their paws isn't always a good thing. They exhibit this behavior because they are feeling uncomfortable or somewhat unwell. When cats are in pain or their paws/limbs are irritated, they try to relieve the pain by licking.
In addition, cats may scratch for psychological reasons. For example, under a lot of stress or when anxious, your cat may scratch itself as it helps relieve its own stress, just like you bite your nails.
4. Claws are a natural behavior for maintaining bodily comfort.
The last possible reason is more natural and simple: your cat enjoys its own paws. When cats use their own paws, they secrete hormones that make them feel comfortable, content, and relaxed.
A cat's breath has a unique scent, and many cats are very happy with their own smell. These scents are released when they rub against their bodies, making them feel comfortable.
Summarize
In general, a cat's paw movements are a natural bodily reflex, and there may be many underlying reasons and meanings. You should always pay attention to your cat and consider various unusual situations. If you are concerned about anything your cat is doing, please contact your veterinarian promptly.
