The russians routinely wake each other up and mean as it is to not sympathise with whoever just got woken... Its cute! They also wander over to the front of the cage and peer at us every 30-60 mins when awake which is also quite cute
Whizz currently asks for a treat on a daily basis which for her is awesome as she's really shy and nervous most of the time (not my fault I gave her one once - I swear I need to find small, safe ham treats and just carry them 24/7 lol)
Skip dives into his "bed" via the window of his house rather than the door which makes me smile
Muffin manages to turn her wheel on a nightly basis. No idea how but it starts one way and has turned near 90 degrees overnight every time we put it back as it was lol
And Scamp... She chews bars to tell us off and/or panic us, and another favourite is to pretend she hates her hamster heaven (extension) all day and then use it on a nightly basis lol
