This is the heartwarming moment four adorable kittens snuggled in a box after being rescued from a pickup truck engine.

A group of workers heard loud meows coming from one of the cars in a parking area in Bangkok, Thailand.

They immediately inspected the vehicles and discovered a litter of kittens under the white Toyota Hilux on July 14.

Footage shows two employees lying on the ground, one carefully pulling the felines out one by one while the other gently holds the rescued cats.

In another clip, the kittens lounged inside a small cardboard box, resting on a red towel.

Moments later, they were seen sleeping in a row with their bellies exposed.

The workers decided to keep one kitten at the office, while the rest were later adopted by other staff members. They also managed to find the mother cat and took her in as well.
