He is chipped yeah, but we only moved into the house 3 weeks ago so I need to change the address (which if you could let me know how to do this that would be great)

He will have been in the new house for 7 weeks when we get back. Do you think that is still too soon? He has been going out almost everyday after the first week we moved in.

I've had cats all my life and have always worried about letting them out for that first time, especially as one of them never came back , but I don't think I can contain him much longer, he's too bloody interested in the outside world!
