It's so out of character, he never wanders far and usually is in and out every 5 minutes. We don't have a cat flap, so he meows at the door to come in/go out. He last went out at 7am and hasn't come back. I'm sick with worry and have had to take the day off work to be here to let him in, if he comes back. We keep him and his brother in during the day when at work. His brother is wandering around the house 'looking' for him. I've walked round and round the neighbourhood calling him and rattling treats. He's only 10 months old and was a very ill kitten when we first got him. He's so special to us, I'm almost in tears thinking something awful has happened to him. He is microchipped, but hasn't got his collar on, which has my mobile number on. I could kick myself for not putting it on him this morning.
