Just that, really. N went out on Monday morning, with her sister R and our much older cat, C, as per usual (well, as per usual for the last week, we only started letting N and R out last week) and she hasn't come back. Not once, not sight nor sound of her. DH and the kids have knocked on all the neighbours doors, we've put up posters, out the poster in the two Facebook lost pets pages for our city, posted the poster on Twitter, emailed all the members of the local residents association...nothing. Nada. R is going spare, she has never been away from her sister for more than 10 mins till now, they both panic if they can't see each other. C also appears to be sad, he keeps looking for N where she normally sits. DD2, whose cat N officially is (R belongs to Dd1, C belongs to DS) is utterly distraught. N is chipped but she wasn't wearing a collar - many years ago my best friend's cat got caught by her collar and died (essentially, she hung herself) so I've been afraid of collars ever since. she's spayed so that should be an indication to anyone who 'found' her that she is owned - yet nobody has returned her and we haven't been contacted. Until Monday she had never left sight of the house - she would go in the patio, venture slightly into the back garden then come charging back to confer with R (repeatedly, like a game). This will be her third night outside. I am sick with worry, about N and about Dd2 and DS who seems just as upset. Our road backs onto (urban) countryside - quite a large wooded area, I'm not sure if it there's a bombs crater there or if the ground is naturally like that, anyway it's a protected area now, despite being in a city) - and there are foxes (and sometimes, cows!). Basically - it's really not safe for her to be out all night. DH has been roaming the area too, we've left food out etc (though not over night, not only are there foxes but, thanks to the bin policy where we live and the service road out the back, there are definitely rats - hence practically every house has at least 1 cat most have more than one). We know there are at least two houses with potentially dangerous (to small cats) dogs too, not that far away (other side of the service road). :(
