I noticed yesterday my bunny wasn't using her back leg she do St look like she wants to put weight on it. I picked her up and there's no obvious sign of injury and she's letting me touch and move the leg not making me think she's in pain or it's broken. I called a vet and they said to keep her caged for 24 hours, dose anyone no how long a sprained bunny leg takes to heal, should I leave her caged for longer? Advice needed thank you
