If it's a small cut, it will probably heal on its own. You only need to leave the neosporin on for about 5 minutes. Just use a small amount and you won't need to wipe it off. Neosporin tastes pretty bad to animals so they usually don't lick it too much.
I suggest that you use the neosporin 3-4 times a day and leave the collar off while you are at work. Cats have a way of gettting tangled in things so it could be more trouble than it's worth.
If you see any redness, oozing or there's a smell to the wound, you should see your vet right away.
Let me know if you have more questions.
