Hippogriff lessons with friends

Claira, Celena, and Jenna managed to con Alexis into letting them go and see SilverNova. Jenna wanted to borrow some of Alexis's and Celena's clothes, so they let her pick out an outfit. All three girls in the front have bags which the keeper of the hippogriffs let them fill with treats.
Not very many fit in said bags, those treats are massive. Only one fit into Celena's and Claira's bags. We managed to squish two into Jenna's bag. 
Really? They were that big?
They were little mice like things, dead, but very ridged.
