There are always exceptions but cats usually at least make one scratch or swipe at covering their scat, or beside it. This is old enough that the scratch in dirt may be gone, though it doesn't look like any was made. Unlikely to be cat.
As to size and shape, that varies so much it doesn't tell much unless we've been observing scat from a particular species regularly enough to know what most of it looks like in that area at that time of year. It changes even with the same animal depending on what its been eating, its health, lots of things. Bears go from logs to squirts, deer from puddle patties to pellets, cats from runny messes to tapered cylinders, and coyotes drop many sizes, shapes and textures depending on what they've been eating.
