This is the adorable moment a cute bat slept with its bear doll in a zoo in Oakland.

Budweiser, the Malayan Flying Fox, cuddled with its brown plushie inside the Wayne and Gladys Valley Children's Zoo in California on December 6.

Footage captured by zookeeper Ashley shows the nocturnal mammal holding onto the teddy bear toy upside down.

The stuffed toy was reportedly donated by one of the zoo visitors.

Keeper Ashley said: 'Budweiser really loves his stuffed toy, and he always clings to it every time he sleeps.'

The management reportedly encourages parents to donate their children's worn-out stuffed toys, which will be upcycled for the animals. They will also offer a 15 percent discount to zoo-goers who purchase a new toy from them when they donate toys.

Malayan flying foxes engage in positive social behaviors, like mutual grooming, as well as negative social behaviors, such as aggression. Play is another behavior that usually occurs among young males.

They are one of the largest bats in the world, with a wingspan of up to 4 ft (1.2 m) and weighing 2.4 lb (1 kg).

This species is listed as Near Threatened by the IUCN. This has prompted zoos and sanctuaries, including the Oakland Zoo, to initiate conservation efforts for these bats. The zoo donates annually to the Lubee Bat Conservancy and supports Bat Conservation International (BCI).
