Having cats is like having children. You can't go to the bathroom by yourself because for what ever reason they want in. Once you let them in they are fascinated with the toilet flushing.
They wake you up in the middle of the night either because they want in your room and your bed or they want to play or they want a treat or all of the above.
I stupidly thought when my kids got older I would be able to "sleep in" heck no. They woke me up at midnight and at 4 am. It's now 5:24 am and I am posting this.
But unlike children these guys will give you unconditional love and they don't ask to borrow the car

then again they have never got stuck underneath solar panels on a neighbor's roof for 3 days
Oh well they will be able to sleep in an hour or so. They have had treats, food and have watched me flush the toilet twice since 4 am
