Has anyone experienced this with their cats...unspoken communication between them. I know I may sound weird, but...

For example, if Dawn is asleep upstairs, under the bed ....dead to the world and if we are playing with Slushy (who is a tuxedo cat) with the laser pointer...and she is having a good time trying to catch that red dot....Dawn will appear as though she was summoned to be there. Ready for the action.
It's as though Slushy called her down.

I can understand sometimes one of them wants attention and meows enough that the other has to check out what is going on...but this is different.

It has happened enough my husband swears they have telepathic ability, but I have to wonder.
