Thanks, JP and bunny Hummeltje! JP writes, "This is Hummeltje (small one in Dutch) a wild bunny we saved from a cat."
Edit: More information on Hummeltje from Nicole, another of Hummeltje's humans! "Hummeltje is a wild bunny. A cat took her out of the nest when she was 5 weeks old. Luckily the cat brought her to the animal shelter Animalhome and they fed her with the bottle until she was strong enough to be placed. We are very very very happy and blessed with her!"
