Carm, I've had cats all my life. I actually own 2 at the moment. Get em spayed/fixed. It's gonna stop him from being in heat all the time, and meowing over and over again. It is agony in a way for the cat since he wants to reproduce, but he can't. Cats go off the instinct of mating to reproduce. Fixing them isn't too expensive also. Many times it's less than 200$, also get him shots for worms or whatever. If you guys never let him out, and he will be a fully domesticated cat, he might be scratching your furniture, if it bothers you guys so much, you can de-nail the front paws, but I don't suggest all 4 paws.
Ask if your curious about anything.
Tru gives good advice also, shows he a kitty lova lova. lol :thumb:
Very good lookin cat by the way, I used to have a striped tabby like that before.
