When we have gone away before we have left the cat a whole load of food in the wendy house out in the back garden. This then allows him to have somewhere dry to eat and sleep if that is what he wants.
We even put a towel in there for him to sleep on.
Unfortunately he didn't see us go on Friday and so we are not sure if he did eat the stuff in the wendy house or if one of the other cats did.
We can't really ask him either because we haven't seen him since Friday afternoon!
Yes that is right, the cat that adopted us has suddenly disappeared.
