So today I took my 691 gram normal female ball python out to feed her a small rat. When I took her out I noticed a high pitch squeaking sound every time she breathed and she also refused her meal. She rarely refuses her meal but when she does, i just try again later that day and she takes it with no problem. But please i need help, do you think she has respiratory problems? If she does i need help on how to treat her preferably without a vet. I do not have the finances to take her to a vet at the moment, how much is it anyway?Any help would be appreciated, thanks!
