A man developed an "extensive" infection that caused his hands to swell after being bitten by a stray cat that was carrying an unknown species of bacteria, a new case report reveals.

The 48-year-old went to an emergency department in the U.K. because of painful swelling that developed in both his hands eight hours after he'd been bitten multiple times by a stray cat.
