I have three great cats.  I love them to death.  I give them lots of
attention both as a group and individually.  

But at night, Storm will not stop crying.  He goes back and forth from
yowling to batting me in the head.  I stick to a very strict feeding
schedule and try very hard not to reward the behavior.  My own
schedule is very regular.  I don't know what to do.  

I could lock him in another room all night, but I feel like that would
be mean.  I play with them as much as I can during the day to keep
them from sleeping and to wear them out.  I just don't know what else
to do.  

Any suggestions?  Please tell me if you have had similar issues and
what has worked.  Or if you have any suggestions.  He is an indoor cat
and so putting him outdoors isn't an option.

Thanks soooooo much!
