Well I just got this 1 yr old ball python from my ex >.>. But more importantly I noticed it may have an RI. Her mouth seems to have some mucus like stuff on it. Also I heard her "whistling". She was in the cold for a bit, because she was in a cold car then outside for like a minute or so. I left her in her tank for a bit then took her out. At first she was not whistling at all and then she hissed but was fine for about 3 minutes, in a humidish room then as I was bringing her back to her tank she whistled some more. I haven't noticed any gaping yet and her tongue is still forked. And she has a retained eyecap -_-. I'm not experienced in dealing with an RI so I was wondering if there were anyways to medicate the snake my self or diagnose it. If I have to bring her to the vet how much will it cost?
