Dozens of you have told me so; I've told dozens of you so ... but I didn't follow the advice... or only part way. I didn't quarantine Monty at all -- and I paid for it with months of war against a mite infestation in both of my terrariums. I quarantined Q for just over one month: I waited for the stool sample: "no internal parasites" , and many weeks of VERY vigilant checking for mites and ticks: no external parasites ... and I was sure I was in the clear.... OR NOT?! When I found out Q was not a male, I wanted to cut my losses and I decided to introduce her into Talyn's terrarium. They got on fine and I was happy to have saved the money on an extra terrarium, heating, lighting, etc. After another month of slowly getting to know my new snake, I found out that she "whistles"... snakes aren't supposed to whistle and if I had kept her in quarantine, I would have caught this before any of my other snakes!! It may take time to find out what is causing her whistling... but the fact remains: I messed up. Talyn could have (and might have) picked up a disease because I cut the quarantine time short. I was so focused on the mites, that I ignored all other things during the quarantine time. Q may have an RI: the vet is unsure because she has NO physical symptoms of illness. (It was only when she put Q's mouth up to her ear, that she heard the sound and said she didn't like it at all.) In the event it is a bacterial infection, she is now on a round of antibiotics. But it could be viral, and then I just have to hope her immune system can handle it and get rid of it. It could, however, be some sort of congenital defect or there is some type of obstruction causing the whistling. Until we find out, or it goes away, she should (and will) be kept away from my other snakes. As soon as Talyn sheds, I will check her over carefully and listen for any noises. If you keep super strict quarantine procedures, good for you!!! Keep it up!! If you don't, or are tempted to cut it short --- think carefully!! A 3-6 month quarantine MINIMUM will save you lots of time, MONEY, heartaches and headaches in the long run. With all the herpaholics on this forum and all the new additions to collections, here is a reminder... don't slack on quarantine!!!
