Feline tracks have a trapezoidal shaped pad with three lobes at the posterior of the pad and sometimes register two lobes at the anterior of the pad. The pad in feline tracks is proportionately larger than it is in canine tracks. The pad area of a canine front track is triangular. The pad area of a canine hind track can be triangular or even round in some species. The pad area of a canine track is not trapezoidal unless the animal slipped forward in mud.
The toe arrangement in feline tracks is asymmetrical and there is a leading toe - toe number 3. The toes in feline tracks are also somewhat tear drop shaped. The toe arrangement in canine tracks is symmetrical and the middle toes are more oval shaped than they are in feline tracks.
If you imagine lines being drawn between each of the pairs of side and middle toes it will form and "X". The lines of the "X" do not bisect the pad in canine tracks but they do bisect the pad in feline tracks.
Finally, felids have to expend energy to extend their claws so their claws typically do not register in their tracks. Canid claws are always extended and often register in their tracks.

Excellent idea to have this ready to refer to. It makes it easier than having to type it over and over. I think I'll have to make a similar post too. Great idea!

Added to the top of my post. Thanks!
Cool. I need to write something up like this too, to add to my iNat identifications. It sure would be nice to not have to type it out every time. :) Meanwhile, I can just refer them to yours. It's excellent.
Nice job on this.
@beartracker and @jim_carretta - Thanks!
Thank you for posting this.
