Are there stoats on there?
I don't think so - not unless they are very big ones. There may be squirrels as well as rats. The bodies were fairly 'old' but not old enough IYSWIM (The S is not See but another sense)

Some of those look like mustelids to me (particularly the paler animals in pic 3, also visible in 6). Collins guide says stoat and rat head/body length about the same.
I'm afraid my nasty, suspicious semi-professional mind wonders what's been getting blootered that's *not* on the gibbet ...
