My 2 youngest are the same way - they always want to try to sleep with Winston, they want to try to clean him, they will work together to try to just annoy him. It is so funny and amusing to watch, because very occasionally Winston will start playing with thim, but it often seems as if he is doing it just to get them to stop bothering him.

Before I got Guinness, it was just Marbles and Winston and Winston would not let marbles anywhere near the bedroom. Winston had decided that it was HIS room and marbles was not allowed in it. Winston would sit in the doorway like a guard and chase Marbles anytime he came near the door.

Then we got Guinness, and Winston tried to do the same thing, but Guinness was persistant and would sneak into the bedroom anyway. at first, this drove Winston crazy - he would pace and he would keep trying to chase Guinness out of the room.

Now, Winston finally gave up on trying to protect "his" bedroom, and both Marbles and Guinness are allowed to enter.... however Winston still protect the "under the bed" area as his own, and Guinnesss and Marbles have accepted this and do not even try to go under the bed.

It's funny though because M and G are always near each other. They sleep together, they play together, they eat together, they even wait for each other to use the litter box and then help clean each other... meanwhile W always manages to be in a different part of the condo (which isn't easy since we have only 750 square feet in our condo)... but if M and G enter a room, W leaves and goes somewhere else. The only time W really wants to be near M and G is if they are getting treats or catnip :D
