How far away might a lost cat wander?
TLDR; A freshly adopted cat got out of his carrier at train transfers and hid in a nearby park in a bush. Is he likely to roam far away or stay in that area for the few days at least?
Story
My sister adopted a cat and he managed to escape when she was changing from train to bus on their way home. Before then they spent about a day together at my parents' house. The cat ran into a large dense bush I hate with body and soul now. We last saw him at 2am and maybe spotted him transfering to another bush at 4 am, but weren't able to catch him as he's quite spooked.
The cat is btw. 10 years old, lived 6 years as a feral and was then caught by the shelter, where he spent the last 3 years. He's been neutered. He gave lazy couch cat vibes, but maybe he's also enjoying the wild again.
We already set up two humane traps in the area and have local forces helping out.
I'm just worried the cat is no longer in that area as we didn't get any signs from the cat afterwards. He might be hiding in the bushes as we cannot see through them. I'm trying to attain a heat-camera to see if we can spot him.
My question
How far around should we look? Is he likely to stay in the area?
