Hi everyone! I'm new to the site. I've had my ball python Mellie since May. She is five years old-- I adopted her from Craigslist. She has always been very healthy--she eats well, has full sheds and is docile and friendly.
Tonight while I was holding her I heard what I can only describe as a "whistle" sound from her nose. It was pretty quiet, and I heard it around 4-5 times. I think she eventually stopped. She is back in her enclosure now, and I haven't heard the whistle--however, it might be because the sound is too quiet for me to hear.
She has no other signs of illness--she doesn't have any discharge and she ate a rat on Sunday. Her behavior is normal as well.
Do you think this whistle warrants a vet visit? Mellie's last shed was approximately one month and one week ago. I am so afraid she might have a respiratory infection. I do not have much money at all and it would be a huge financial strain, but she is worth it to me because I love her so much.
Thank you so much for the advice. I am so worried.
