The joys of kitty ownership. Or being owned by a kitty! I'm sure once he gets used to the flow of your home that he will let you sleep in.... till at least 6!
Mine do the same thing. If I close the door they are at it batting and putting their little paws under it trying to open it. Much easier to give in and grab a nap later.
I keep two mugs filled with fresh water in my sink. I also have a bowl on the floor. All five house kitties prefer the mugs in the sink to the bowl. Kitties are funny that way.
Rascal sure looks like he has settled in for the count.
