She was fine, no noise when I had her out, even when she was close to my ear. But when I was putting her back, she started to make the noise.

It was when she breathed out, it sorted reminded me of a hiss but wasn't?

Her hot is 91-92. Doesn't go any lower then 88.
Cold is 80-82. Humidity is at 55+.

Like I said before she hasn't shed for two+ weeks. She only shed once which was back at the end of August/first of September. Never heard her make the noise before.
