Should I try to cut them off short???
If it were me, I'd cut them...and if you do, a pair of sharp shears will do a fine job.
Another trick I can tell you is this:
Unless you're trying to dry in cold temps, a fox shouldn't be 'skin side out' for more than 24-36 hours, if that.
Anymore isn't needed and if it's too dry, it will be hard to turn.
If it's not sticky and dry to the touch, it's good enough to turn fur side out and put back on the stretcher.
When you do turn it, take a wad of newspaper and stuff it inside the foxes head area.
About the size of a softball, or slightly smaller is the size you want.
This will cause the head to finish drying to that form and make the head shape and ears perk up!
This simple trick, gives the finished pelt a much nicer look.
Brush the fur up backward,toward the head and leave it.
Now when you go to sell it, simply take the pelt by the nose and 'gently' shake it.
The fur will fluff up and go back to it's natural shape.
Don't forget to take your index and middle finger and run up the tail, from tip toward the pelt a few times>
This fluffs up the tail, giving it a nicer look.
Fox fur sells by 'looks', don't let anyone tell you different!
