That’s a tough one. There is a spray you can get, Bitter Apple. Most cats hate the smell and will avoid it. In your shoes, I would get some and spray a little on a wash cloth or similar and tuck it in the sling. That may keep him from crowding the sling and stepping on your injury. Don’t spray yourself or your sling directly though. If the odor is too offensive and makes him stay away entirely, you can toss the washcloth in the laundry and try something else.

Bitter Apple Spray - Note, this talks about the spray as a chewing deterrent, but in my experience cats will avoid areas where it’s been sprayed. Just remember to start small. You wouldn’t want your boy to start avoiding you completely.
