I believe most indoor cats,if they get out somehow, are terrified, and I don't think they go to far from home. They could be under your deck,porch,behind bushes along the house. They may hide during the day and come out at dusk to hunt for food and because it is quieter. My indoor cat snuck out a while back and I put out her smelly cat food and went out and called (talked) throughout the night shook a bag of cat treats. I didn't yell her name but gently called,took my flashlight too. Around 2-3am I grabbed her eating her cat food. This worked for me. I was lucky. Just a suggestion. Good luck! It may be inconvenient for you to wake up early in the morning before dawn to look for your cat but over the years if ever there was a stray on my porch it was before sunrise. This is your cat you are looking for and you just may find it then, I think it was worth it.
ALSO, if during the day you can call out to your cat in the front and back of your house. Your pet may hear your voice and come running. Your cat also may be close to home and if it is an indoor cat is freaked out and may hide. Under a deck or porch, in a garage or shed. Cats like it quiet and will not like noises like the lawnmower going or other loud noises. Good luck finding your pet! Post on a site called "for the love of louie" for your lost or found pet. Don't stop looking and check at your local vet offices many times they have a bulletin board where lost or found pets pictures are posted. You could put posters up on telephone poles or trees with LOST CAT/DOG and your phone number, large enough for passers-by to see. Don't stop looking and good luck.
