My cat disappeared?!

Hi. I'm Rae, and my cat vanished. He is a rather large cat, neutered, about two years old, and grew up as a barn cat. We've been letting him out since we got him, since that is what he enjoys most, and gets very irritable and even more crabby than usual if inside too much. We let him out, as normal, four or so days ago, and he hasn't been inside since. That is not typical of him, he is gone for a day and the half at the most, granted he was out for a few days last year, but that was once. Is this normal behavior, and if he is okay, will he come home?

HI @BarnOwl .  Welcome to TCS and so sorry about the lack of reply.

Any sign of your boy yet?

So sorry to hear that your cat is missing, do you have any neighbors or anyone nearby who is familiar with your cat that you might be able to ask if they have seen him around?
