Pallas' cat kitten playing with dead mouse at Nordens Ark

A few hours after being fed quite a few chicks this Pallas' cat kitten has caught a mouse that was stupid enough to enter the enclosure with four predators (Mum and her three cubs). The kitten made a kill and started playing with the natural enrichment, while a littermate wants to participate in the game or just steal the mouse. The latter option is more plausible I assume. Watch the littermate making stealthy movements to surprise the other and capture the mouse. But that is not going to happen!
