Hello I am new to these forums. I have 2 cats both are young. The normal cat is an american shorthair, dark colored. He is a rescue, and was neutered from an early age. I first lived at my wifes brothers house, now I have my own apartment. The orange cat is a Somali long haired cat, who just randomly showed up at my wifes parents house, meowing. They gave it to her brother, who gave me both cats upon getting an apartment. The orange cat was not neutered. He kept meowing at night, always getting outside,.,.,./, and spraying all over. We chose the cheap neuter option, the 40 dollar neutering at the local shelter. He came back, and it still appears he has his balls, but whatever. Since then he stopped meowing at my bedroom door. We got him neutered when i was living at my wife's brother's house. After the neutering, every few days for a half hour, he would act crazy, and start meowing, and peeing, and hissing. He runs into a corner, and does this. Since I moved in my apartment, he acted a bit better. But every 3-4 days he gets into this rage mood, and starts meowing, and hissing, and growling, and runs away to a corner. It stops after an hour and he is normal. What is this?! It is annoying! Why cant he be normal like the other cat?!?! He then sits in his corner and growls. Hopefully someone here can help me with this, because I am not a cat behavioral expert. Thanks!
