Let's have a go. All of this is conditional on Giggles not getting out of the way of being touched.

Charm test to look non threatening
vs. Fel 45
(1d100)[33]

Channeling test
vs Wp 51 (+10 aetheric attunement)
(1d100)[69]

Casting roll for sleep is 6+ (+1 if channeling is passed)
(1d10)[3]

If this doesn't work at least Giggles will be focused on Andrei.
