Theo is missing...

...and has been since Tuesday afternoon. I know he's a cat and is probably doing what cats do but I'm so worried about him. He didn't come in for his tea yesterday....very unusual...and no sign of him today. He has never been out at night before. It has been windy and raining most of today...and Theo hates wind and rain. I've asked round the neighbours but nobody has seen him. I'm trying not to think the worst though and hope that he is ok and just got a bit lost...and hoping someone is giving him shelter.
