Will my rabbit die if she don't mate?

Are you taking the doe to the bucks cage??? Place the doe in a warm area with lots of light (so she realizes that it is summertime and time to mate) for a couple of days then take her to the bucks cage. If she still refuses to mate place her in a cage beside the buck or leave her in the bucks cage (so she can smell him) and remove your buck to another cage. Never put them in a cage together and walk away. Does have been known to castrate and/or badly injure bucks. Still reluctant???? Did you put them together and walk away??? She may already be pregnant and you missed the actual act, dude.
