It's mid winter where we are (we have snow from the end of October-April) and she went from being an outside rabbit to inside December 9th, I have taken her outside for 5 minutes on nice days cuz she seems to still have very thick fur.
So I have had this bunny for about a month and her ears recently started doing this. She is a Californian x New Zealand and she is 8- 8 1/2 months old.
