I agree with Pam, they get better when they're older. Casper & Kitty are still babies and have a lot to learn.

Mine are almost always angels. During daytime they're in & out the house, playing in the garden, taking sunbaths on the garden table (Eddy), playing peekaboo in the tree (Rudie). They come in when I call them, they sleep peacefully, they never run around the house, they don't break things, etc.

The only time they're not so sweet, is when it's night and they want to go out. That's between 2am and 5 am. Rudie scratches the (new) carpet which is glued to the floor. I'm very disturbed by this nightly anger, so he now spends the night in the livingroom with the doors locked.
And when he goes through his periods of denying every food.... grh!
Or when he sits outside and won't get in when I open the door.... grh!

Eddy is a real princess. She's sweet and peaceful. An absolutel angel.
