My 6 month old male moggie hates being inside at night. He wails so loud, it sounds like I'm torturing him! If I let him out, I know he'll get into fights.

Maybe you need to have a hard play with him for an hour before bed time. Wear him out and maybe he'll sleep throughout the night. And, you are right, you should NOT let your cat out at night, because they do roam and get into mischief.

I'll give that a try and let you know!

Hi, KatK!
Sounds like you have your hands full. Here's something else to try if hard playing doesn't do the trick...
Firstly, you have to realise that cats are creatures of habit and they will do well with a set routine. That means consistency in your treatment of him. Pick a place where you want your cat to sleep, preferrably a place where you can confine him, and put him to bed every night at roughly the same time. This sets a routine. No matter how much the cat complains and howls, don't give in and let him out from pity or frustration. Eventually, he'll get used to the routine and should sleep thru the night. It might be good to get him a nice, snuggly bed so he'll have a comfy place to sleep.
Maybe do a heavy play session, then do the routine bed thing. Good Luck!!

I put my 4 yr old tom in the garage with a heat pad. For some reason it seems to make him happier than being inside the house at night.

my 4 yr old cat patch doesnt care where she is. she liks 2 sleep in da house though i used 2 live in town an she used 2 go roaming now she hangs just out side the house and meows
