Lost Black Cat 'MayMay' in Whitehorse

We found him in the bushes in our back yard! It's just besides the rear fence and there is a small opening leads to the other property at the rear. He captured a pigeon on the lawn and took it into the bush to kill. We tried to grab him but apparently he did not recognise us and slipped away from our hands, he scratched my partner's arm and chest. He went back into the rear property and hide himself, we placed his litter box at the rear door of our house and his food as well, hopefully he remembers that this is his home. Fortunately he did not wander far and we can just notify the surrounding neighbours to be aware. Any tips for capturing him in the wild would be appreciated.
