Ball Python is making weird noises :(

Hi,

Yesterday I fed my BP a small rat and ever since, she has been making a weird hissing noise. It's not quite a wheeze, it kinda sounds like she's sniffing when she does it. She also makes popping noises when she moves. Could she have gotten some dirt stuck in her windpipe or something? Any help is appreciated!

Thanks,
Glenn.

Is the snake in shed?
Has the snake shed recently?
Is it yawning a lot also?

When they start a shed period the skin will come loose on the face first, sometimes creating a whistling noise.
