A council has released footage showing a family of nesting squirrels sniffing around a roadside drain.
Hertfordshire County Council said it was one of 11 unusual finds in their roadside drains, which has included a trampoline, pair of trousers and a hand grenade.
On 4 November, the local authority started a programme aimed at cleaning at least 520 drains in 80 roads.
Liberal Democrat councillor Stephen Giles-Medhurst OBE, who is the executive member for highways, commended his staff for working hard to “keep gullies clear”.
