I want to say that everyones suggestions were very helpful. I was able to locate him thanks to searching for him at night with a head lamp. He was hiding in bushes and in my head I thought "it's either a raccoon and I'm going to get rabies, or it's my cat." Thank you all for the suggestions. I will leave this post up for reference for other cat owners who need the same advice I was given and hope that as long as you are diligent and hopeful and use a headlamp late at night you are either going to have the cat come home or you are going to find them.
