My cat is attacking me!

I basically made an account on here because I can't find any research online be to help me and I'm hoping someone on here can. I had my cat for about a year now, his mom was a stray and she got pregnant by possibly a neighbor's cat so I'm not sure what breed (if any specific one) he is. Anyway he's always been a super loving, and very laid back kitty, always rubbing against people and napping on me. When he was about 6 months he started biting me when I stopped petting him or didn't pet him when he bumped his head on my arm. He was always gentle and only did it once or twice to get my attention so I gave in and would pet him. He progressively got worse and would occasionally trap my whole arm under him and keep biting me hard until he got what he wanted... Well for a long time I thought he was a girl (he was the runt) so I never saw it as a dominance thing. After he was neutered and we were told he was a boy my family and I were shocked but it explained a lot of his territorial behavior. But now he's worse than ever, chewing up cords, running and jumping through the house and randomly attacking me. It's gotten so bad that I have to walk slowly through the house and oftentimes carry my spray bottle with me to keep my feet safe... Any ideas on how to curb this behavior? Anything helps, thank you.

It sounds like he's got a ton of energy. The biggest single thing you can do is have regular interactive playtime with him at least once a day, preferably twice or more. The aim is to simulate the hunt for him. The best toys for this are rod and line toys such as Da Bird. If you're able to wear him out with play, his prey drive will be satisfied to a degree and he'll be less likely to see you (or your home) as targets. If he does get you, freeze. Prey isn't interesting once it's 'dead'. Hissing at him might help too - its the way one cat tells another that they've crossed the line.

For the short term, it might be worth considering fitting him with softpaws claw covers so that he can't actually hurt you.
