Kittens purr for various reasons, and it is a way of communication with their mothers and humans. Here are some reasons why kittens purr:

• Bonding: Kittens start to purr when they are only a few days old as a way to communicate and bond with their mothers. They also purr to bond with their human companions.

• Comfort: Purring is a sound of contentment, and a clever kitten will use it to get more than their share of stroking. Cats might also purr in very stressful situations – it seems they can actually calm themselves down by purring.

• Location signal: Because they’re born blind and deaf, kittens need an alternative way to locate their mother. When it’s time for milk, kittens are guided by the vibrations of their mother’s purr. A kitten will also purr loudly to make it easier for their mother to find them.

• Happiness: Purring is often a cats way of saying they like being touched and want more. A purring kitten is a happy kitten.

• Asking for something: Cats purr while eating or drinking to express feelings of happiness and fulfillment, and they might also purr while asking for something, such as food.

• Self-soothing: Cats may also purr while stressed or anxious, like when visiting the vet. If your cat is nervous, purring can be a way for them to self-soothe and calm down.

In summary, kittens purr for various reasons, including bonding, comfort, location signal, happiness, asking for something, and self-soothing.
