thumping?

so i was awaken by some thumping coming from my leopards cage? this is the new leopard that i just bought two three weeks ago, the blazing blizzard someone told me that she is? but yea um so i go up to it and shes biting at the glass? i put my hand in side and she quickly turns at me and stares then she throws her self at me and bites me lol not once twice? i havent seen her eat since i bought her so i get one my crickets and i hold it it front of her and she looks and bites and misses and bites again and she got it... she sits ther for a good two min then i try to pick her up the she dashes to her cave as fast she can lol... and she can run for not having her front hand lol

If she continues that behavior of hitting the glass, you might want to cover up the side of the tank. She may be seeing something outside the tank that she thinks she can eat.
