No need to be embarrassed, the cat was black and white, though ;-)

You are all right with your comments to keep the cat in the flat, for a week at least - that was also my plan, but all I wanted was to be nice to him, as he kept looking out of the window into the garden - now, I won't let him out for a bit, I am still too worried, more because of the foxes than that he really might get lost, to be honest. Just a shame for him as we are both at work during the day, at the moment - still, he is cat and I am sure he will manage...

Thanks for all your help and nice comments again!
