Could use some advice regarding my rescued feral

Some ferals are just more accepting to the human touch more so than others. I had a "true" barn feral who allowed me to touch his head, with one finger while he ate. It took weeks but eventually he allowed me to pet him more and more. And, then eventually he started rubbing up against my legs. One of my released feral's, Dixie, was easily handled at the shelter and for her TNR, but she was extremely fierce and aggressive and would never tolerate ANY petting while she was in my care recovering from surgery and recently a leg infection. I just think she allowed to be handled at the shelter and the vets because she was in over her head and so fearful that she was frozen in fear. BUT having said that, I think these types are the ones who can come around quickly and be socialized/trusting with one person. This may be the way your guy is. It is possible that at one point early in his life he was someone's pet and got lost and totally reverted back to his wild roots. If so, you would have that in your favor as you progress with his socialization. Be very careful about trying to pet too much until he is neutered. He will get overstimulated quickly and become very aggressive and swift about it. Once he is neutered it will take about a month for his hormones to calm down and he will be more willing to accept a relationship with you. He is a very good looking, beautiful cat

I have to point out that you can't see cat if cat does not want to be seen, hiding and scouting is what they were 'made' for, when I did move to my house there was two small cats, I never saw them more than twice, but even next year I saw paw prints at my warehouse, thinking it was some random cat, but warehouse has been feral hideout for really a long time, there has been ferals living there lot more than I have seen, after setting up cameras, reality become much clearer to me, there were so many of them.

Also with my current three it has happened more than once that cat get spooked as I simply can't see one which is right next to chair spying on me while hiding, so when I walk to other room past the chair cat runs like fire under it's tail, they are not quite tame yet, still hiding during day and it has been almost a year, but petting has become now possible, only when they are willing, though.

It can't be known what horrors your poor cat has been trough, it may take quite some time for wounds to heal, especially wounds that are in mind, when Tiger learns that you are different from what experiences he may have, who knows maybe he has been hit fit hand or kicked with leg, surely one gets very cautious about those things then, or maybe someone has chased him off from their lawns/porch so that makes some wounds which must be healed first.

Having him neutered helps in 1 month really lot, at least from my (very little) experience, just be patient, he shows up when he has made his judgement, he probably will test your nerves too, making mess, dropping something from shelf, mine did toss large window glass to ground as it was leaning against the wall in storage, most likely just to see what is my reaction and if I'm worth of their trust.

Also must be said, if I was put to situation of my cats, I would for sure be the same, getting captured and vet where neutered and then bring to new odd place where huge two legged monster is moving around, who would not be afraid and later testing if monster will really not be a monster
