Dh went out to do the school run and she wouldn't come in. I came in from work to a note saying she was out in the garden so I opened the door and there was no sign of her. I rattled her Dreamies bag, but nothing.
We think she may have got into one of the empty houses as we live on a new estate and they're still building. Dh asked some of the workmen, but they hadn't seen her. The doors on the empty houses are left open during the day then locked at home time.
I'm going to make some messages and put them through people's doors. We live on a small estate and there's no main roads nearby.
I feel sick, she's not a year old yet and she'll be frightened 
she usually never goes out if the immediate vicinity, but the workman said he'd seen her playing at the end of the row possibly with another cat - a tabby whom I've seen around. She is very sociable due to coming from a large family.
