While I would generally say that is true, some kitties just have personality problems. I have rescued every single kitty I have ever come across that needed it. But some can never recover mentally from the trauma, and some kitties are just meaner than snakes. But I love them all just the same.
My whole life I have been around orange toms. My Grpa loved kitties, and he always had a big ol orange boy. Several of them.
Now my Dad has one who hangs out in his shop. They are just the sturdiest little creatures. I have no idea why.
I have never had one myself. But I have always wanted one. My sister recently adopted two from her local HS. Great personalities.
My current three, all rescues, are on my page.
Perhaps I have just chosen my ferals carefully ... I have never failed. Once the trust is established [it usually takes me about six months] they become overly trusting and I have had to keep them indoors.
A word of warning: Do not bring a feral cat into your home with your established, healthy cats. I have the means to keep a feral in a completely separate building while they are being tamed. They must be vetted immediately and then, after that, kept separate for quite a while to be absolutely certain that they do not bring anything harmful to your other cats.
