Yep, but I only have 3 cats. Bo is big, and jumps on the bed with a big clunk. Abby has a much lighter jump. Abby also always tells me she's near, with a soft "mrrrow". Bo is pretty much silent.

Bo's fur is thicker, Abby's fur is softer & silkier. I can tell when Hanna the kitten jumps up, because she's the one moving at 100 MPH - she doesn't do anything slow, yet. And she's littler than the other two.

That's about the only time we are all in the dark - bedtime.
