I would avoid bandages and gauze, use salt water only.
Recently our feral cat Milly had an injured paw, 2 bones chipped, claw ripped out and cut, she didnt get it dirty in her tray and it didnt get infected,unless this is a massive cut stop worrying.
If you are overly worried you can ring the out of hours vet for advice only.
Hope Basils paw is soon as good as new.
