Beside myself with worry as one of my indoor cats has gone missing. The kids have the door open all the time to play outside and I've not noticed she's gone out and she's still not back. She usually only ventures into our garden/sometimes the next door one but is back when she hears the front door shut. She usually sits meowing until she's let in. I'm so upset. She's never been gone this long. I've put a comfortable box and one of her cushions outside but otherwise I'm convinced she's been run over. She is chipped but I don't know the microchip number (yes I know, terrible). Me and my husband have been round and looked all over. What else can I do?!
