I just bought, pre-scented, and gave my snake a live mouse.

I got excited, it looked like it was going to eat, it followed it with it's head, then it would sniff it out with its tounge and turn away and just ball up.

WHY?!

So I just gave it a dead mouse, and it did the exact same thing.

I'm honestly getting really stressed over this, what should I do?

Even the new ball python at petsmart (had it for one day) ate. WHY?!
