Video of the day: tigers get blood lollies to keep cool at London Zoo

Staff at London Zoo have come up with a novel way to keep their tigers cool: by giving them blood lollies.

While we might prefer chocolate and vanilla ice creams, the tigers get very excited about the unusual ice lollies, made with the blood from their meat.

Meanwhile, the gorillas also have their own unique way of staying cool: giant ice cubes with sunflower seeds frozen inside.

But it's not just about stopping them from getting too hot in the Easter heatwave.

The zookeepers say they like to keep their animals active with different challenges and activities.
