If you find a cat and it responds to your call in a friendly manner by approaching you, it is probably owned. If it is identified with a collar and tag, you can call the owner yourself.
If the cat has an “M” tattooed in its ear, it indicates that it is microchipped in which case you will need to take it to a vet or your council so the chip can be scanned for owner details. If the cat has no visible ID, it will still need to be scanned for a microchip.
If the stray cat appears to be a lactating female, try to locate her nest and kittens and relocate them all to a vet or animal shelter.
If the cat looks sick or distressed or has kittens, call the RSPCA (SA) Inc, on 8231 6931 who will be able to provide you with further advice.
