>aproaching stranger,even eating from him
Nice fake story
cat probably has flees, dont let her inside bro wtf
let it roam and stop putting NA thoughts into cat's head by feeding him
TBH you should never feed stray cats, they just keep coming back to you for more food instead of heading to their possible home.
Anyway, since you've already fked it up, i'd ask in a local FB-group or try bringing it in to a vet to see if it has a microchip planted.
