1) Neutering your cat will certainly help to reduce the likelihood of your cat, male or female from straying.
2) Get your cat microchipped, if it is found all vets and pet rescue homes will have a microchip reader and will be able to call you right away if your cat has been or injured.
3) A personalised breakaway cat collar printed with your phone number also means you can be contacted sooner if your cat gets lost or injured. There are some brilliant ones available have a look at http://www.kittycollars.co.uk/
Please note it is important, that you only use a breakaway cat collar which is designed to snap open quickly if caught on anything. So if your cat is in danger - hooked on a tree branch, snagged on a fence, caught on a window latch - she can break free.
Anyone who has ever had a missing cat knows how worrying it is, not knowing what has happened.
Most indoor-only cats tend not to travel far. While an adventurous indoor/outdoor cat is more likely to roam, a scared cat may not trust their inner compass, get confused and get lost. Once a cat has wandered out of their comfort zone anything can happen to scare them further: Barking dogs, wildlife, loud traffic noise, teasing school kids, the list is endless.
*Start searching immediately. If you conduct an extensive search immediately, there's a good chance you'll find the cat close to the location where it was lost.[The more time has passed increases the opportunity for the cat to roam further from home.
*Stay calm. It is natural to feel upset, but getting into a panic won't help you or your cat. Taking action immediately can ease the anxiety.
If you recently moved, go back to your old place and search. If you moved really far from your original home, ask friends, family, the postman and old neighbors who are still living there to search for you.
*Call quietly for the cat. Don't assume your cat will respond to your voice as it normally does. A lost cat is usually a terrified cat, and may not want to leave its hiding spot even for you. Call for it in a soft, quiet voice, to avoid scaring the cat further.
* Stop and listen regularly. A cat that is trapped, hurt or hungry will likely meow. We often hear of cats trapped in garages and sheds etc.
* If you have dogs, their enthusiasm may frighten your cat during the search. However, if your dog enjoys looking for the cat or responds to "Find the cat," it may be useful to bring the dog if you can't find the cat yourself.
*Call all the vets in the area to see if your cat has been found and brought in by a worried passer-by. The cat may have even been brought in injured by a well-meaning stranger who didn’t know where it belonged.
* If, after a time the cat still hasn’t return try the cat rescue centers in your area.
* Making and putting up a poster, even offering a small reward can increase the chances of others looking out for him/her.
