Lazer toy and Flying Frenzie, we have 2 plus various attachments.
I have a play session just before bed with the lazer, followed by some Dreamies, then a more settled night. Our Ollie is a little tinker, and loves cuddles in the early hours, this week for some reason at 1.25 ish.
If he doesn't have a good play before bed, he keeps pestering the older cats to play.
