Cat Problems

I do not know what is wrong with my cat but he was up all night screeching and meowing loudly driving me crazy. I decided that it could be because of his male hormones so determined to have him neutered in the first of February. He is screeching again tonight which is getting on my nerves a lot. I do not know what to make of him. I took him outdoors for awhile. I think that he is probably a bit stircrazy but whenever the slightest sound occurs outdoors he quickly runs indoors. He has not become used to outdoor sounds yet at all so he is in a real dilemma as to what to do. I will try to get some sleep tonight...meow!
