In a houseful of cats, we've rescued too many to mention. My favourites were always the itty-bitty tiny baby newborn bunnies, so small they would fit in a coffee cup. Usually the cats were nice and brought them to us whole, so I could try to keep them alive and release them later.
One time, a dog at the stables where Rue worked caught one. We had a nesting box in our cockatiels' cage which they weren't using. It was dark, quiet, cozy and out of the reach of the cats, so we kept the bunny in there for about a week before we were able to release it, safe and sound. I wonder if it does wolf whistles now like the 'tiels?*bg*
