Hi Schmoo!
Nope, just like teenagers at the weekend, let them get up when they're good and ready.
Shouldn't be long now, with the weather on the turn (it's the Vernal Equinox this Saturday). Much like with Bagpuss and friends, I expect one will wake up as soon as the other does.
Might be worth making sure they have fresh water in a non-catapulting bowl ready nearby, and maybe some suitable food. Put dry (i.e. non-fresh) food out just now, in case they're away with the fairies for another week or two.
Good luck with them, and stay in touch!
