Could well be. Fox pooh is black, tapered to a point at one

(often with an upward twist) and smaller diameter than you'd
expect from an animal that size. They will often deposit one on
top of some raised object like a stone . You might also notice
scuffs on the grass where they've been loking for worms, or that
balls and dog toys have moved round the garden overnight.

If it contains significant amounts of hair or feathers, it is fox.
I find it tricky to tell fox scat that does not from hedgehog, and
should be interested to hear of a reliable way of doing so.

My "Shit Book", aka Bang & Dahlstrom, _Collins Guide to Animal Tracks
and Signs_, agrees with Janet, saying fox droppings "are
sausage-shaped, usually 8-10 cm long and c. 2 cm across and with a
spirally-twisted point at one end." If the dropping is broken up,
only one bit has the point. It makes no mention of lawns as a likely
site, though it's possible if a fox has a regular path across a
particular lawn; in general they leave them on a slight elevation,
allowing scent-marking to take better effect. Hedgehog droppings, on
the other hand, usually have a point at one end, but there's no
mention of a twist. "The size is very variable, but on average each
dropping is 3-4 cm long and 8-10 mm thick." "...they can be found
distributed at random on, for instance, lawns..." I infer that fox
droppings are black only in autumn when they've been eating berries,
while hedgehog ones are black all the year round.
