I got my cheeky new cat last Tuesday and I've had lots of conflicting advice about when to let him out. The RSPCA lady said 5-6 weeks, the cattery told me 2-3 weeks and other people have said they let their cats out after only 3 days to a week!
I'm not in a rush to throw him out
but he was starved when the rescue got him and so he's now completely food mad. He can also open doors! It would be handy to let him out while we're preparing/eating food.
He's quite confident and seems to have settled in well but it's hard to tell. How long have you kept yours in?
