He came in as a feral and originally had another name, but that was so long ago that nobody seems to remember what it was. Somewhere along the way he started to be called Ollie, and it just sort of stuck. Sometimes cats’ names change over time. They don’t seem to mind.
In his old age, Ollie is less wild than he once was and accept treats (or sniff a finger to investigate the possibility of treats), but he’s doesn’t really want to be touched. Luckily, he’s got human protectors in the sanctuary staff, who keep him comfortable and safe but don’t ask more of him than he’s comfortable with.
