The other day Jan asked:
"What is this animal? It has long back legs. It has a white mark on its head. It has a light-coloured tummy. It has a dark patch under each eye. It’s just over a week old and its eyes are just starting to open".
It is a wild European rabbit. The dark patch under the eyes and the white patch on the head are common variants, just mentioned to throw folks off their guard. It is just over a week old, and it (and 4 other siblings) are being fostered by a domestic rabbit with 5 babies of her own, which are the same age.
