We have had our rescue cat for a couple of months, and have just started letting him outside. He's 5 years old, and was only neutered by the rescue centre just before we got him.
He likes going outside, and disappears in the blink of an eye. He doesn't come back when you call him from the house - a couple of times he has wandered in after a couple of hours, and on two other occasions I have got worried after a few hours and walked around the streets calling him (after fruitlessly calling from the back door). He has reappeared at the back door both times within about 5-10 minutes of me going out to call him - he was out about 4 and a half hours today.
So my question really is, what is a normal amount of time to be out, in nice weather, for a cat his age (as I said, he's 5). I find it worrying that he is "missing" for such a long time, but is that just a male thing? The previous cat I lived with was a young female belonging to my housemate. She would bob in and out of the catflap, but would always come when you called her, and would always be waiting at the front door when you arrived home.
Is 4 hours normal - or would it have been much longer if I hadn't gone out calling and he is rolling his eyes at me like a wayward teen as he shuffles reluctantly home?
(He seems happy enough now he is back, washing himself on the spare bed)
