We met three wombats that day and all of them were found in their mothers pouches after being hit by cars. Thankfully a local volunteer takes them in and cares for them until they can be released back into the wild.
Even as young wombats they have long claws and tough butts. As adults they can use their leathery rumps to crush snakes and other creatures that try to invade their burrows.
Young wombats like humans and cuddles. However, once they become 'teenagers' that all changes and they become the stereotypical grumpy and solitary wombat people know (and love!).
If you can buy or borrow a copy, I'd recommend 'Diary of a Wombat' by Jackie French for more about wombat adventures. She based the story on her own experiences with wombats on her property.
