Cassie and Saffron only work in tandem if there is a VERY large moth or if they think it's time for breakfast. But yes, the little black siblings will often tag-team whatever it is they are chasing. Ninja goes high, Nuit goes low. But they don't sleep with me as much.

If Saffron could split herself into two cats for better efficiency both in keeping me awake and in chasing bugs, I am sure she would do it.
