4 animals came out of the hedge onto a deserted lane and started crossing it. It was near dark on a summers evening- say 9pm?
Some were more cautious than others. One came up and sniffed my foot while another one hissed. They went to and fro for a couple of minutes, several times in clear view.
They definitely had the colouring on the pictures of polecats and looked just like them. I assume they were youngsters. It was a lovely experience.
It would be nice to have a more expert opinion!
