They're beautiful, but would definitely need to be checked over. At the very least, they'd need flea treatment.
They're incredibly timid and not socialised at all, which is probably a good thing with that many drunks wandering around ! But cats can get socialised quickly if you give them enough love and food 😁 Most of our cats have come to us as badly-socialised rescues, and Sooty was totally feral but became a wonderful friend.
yeah, it's difficult as they get older. not impossible, but difficult. I adore cats. I would adopt them all if I could.
