Today in Adelaide it has reached a massive 43 degrees celsius - well over 100 degrees farenheit. My baby bunnies are inside at the moment in their hutch but I feel bad keeping them cooped up! So if I did put them outside for a while in their pen (in the evening or morning when it's cooler) how can I keep them from overheating? How could I keep them more entertained inside their hutch? Or how can I make a wee wee-safe indoors pen? Thanks!
