Don't give up hope. On the English forum's, cats come home after weeks or months of being missing.

Just keep visiting the shelters & vets and keep calling for her everynight. Sadly also check with who ever clears the roads

Try posting posters further a field now, i.e. several streets away. She might have wandered further in several days.

Also check if there were any strange car or vans in the area when she went missing, cats frequently wander into delivery or moving vans and travel to other towns etc.

Also find out who are the local feeders in your community, if Maggie is lost she might turn up on a porch to be fed alongside strays. Give a copy of your lost poster to all the feeders of colonies.

Although 4/5 days is a long time to be waiting, keep your chin up and keep looking.
