Please invest in some frozen bricks - you know the ones you get for your esky? and have them ready for your bunny for hot days. Bunnies just can't handle heat so whenever it gets over 28 degrees I have 3 of these I put in my bunny cage amd he lies on them to keep cool, I make sure he is in the shade and when its really really hot I bring him inside and place a fanand him and his ice bricks in the laundry with the cord up high so he can't eat it!
Bunnies are awesome pets but beware summer!!!

PS sorry if you already know this! I have had 3 people I know accidently kill their bunnies in the heat.
