Megabattie posted a video of a female grey-headed flying fox who is "happy to stuff her face" with grapes.
Green grapes, red grapes – any grapes.
This bat is not a pet – she's a wild animal who was rescued, nursed back to health, and released, fatter and healthier, and still pregnant, about 6 weeks after she was rescued, almost dead.
Do not handle bats unless you're vaccinated and trained. Some bats (a very small percentage) may carry deadly viruses.
Call a wildlife group if you find a bat in trouble. If you get bitten or scratched, go to your local hospital and you will be vaccinated free of charge (in Australia).
Bats are nothing to be scared of if you leave them alone.
