This is the heartwarming moment a pet cat comforted its anxious owner during a restless night.

The woman struggled to sleep during the Ghost Festival, prompting the tri-coloured furry creature to sleep next to her in Zhejiang, China, on August 24.

Footage shows the woman tossing and turning in bed. Her partner can be seen patting her back, and the feline eventually hopped into the bed to cuddle with her.

Cats can understand distress and other negative emotions in their owners through behavioural and vocal cues.

The Zhongyuan Festival, or Ghost Festival, originates from ancient Buddhist and Taoist beliefs, where restless ghosts wander the earth in search of food and entertainment. At these times, ghosts are believed to be powerful and can bring negative energies into people's home.
