You can tame a feral cat
First, put a trap where you see the cat the most and put fresh food in it at the same time daily. Once caught, keep it away from other animals and get to the vet immediately. Give it a quiet, dark, cat-proofed room with food, water, a place to hide, litter box, and clothes with your scent on them. Leave it to rest for 24 hours and when you go in be prepared. Wear long sleeves, long pants, gloves, shoes and cardboard shield.
