18 months old, neutered. He was an indoor cat until a few weeks ago, then I did some recall training with him, which appeared to work. I built up from 2 mins in the garden to letting him out on his own in the evening. A week ago he started going into next door's garden (actual jungle), 3 days ago he buggered ofc for three hours, then 2 days ago, about 5. Last night he didn't come home. I sat up until 4am (daft!) Then left kitchen window open for him.
Very worried now! Any advice? Is it worth going hunting for him or is he likely to just stroll up in a couple of days?
