I know. As far as I can find, only ammonia can kill crypto.
Dakski is right that I don't know what is going on, but I need to assume worst case. I apologize that I haven't given updates today, but I've been quite busy. I've been cleaning and doing what ever I could to do the best for my BEL. Her enclosure has been scrubbed, cleaned, aired out, and refurbished. A stressful day for her, and myself.
I haven't gone to Grafton and don't plan on it. I know about ER VET in Grafton, Mass. They actually did a vasectomy on one of my cats; not neuter, a vasectomy (long story). But In Weymouth, Mass., we have the Oddpet Vet. They focus on snakes and other reptiles and the doctor I'm seeing specializes in boas. So, I'll wait to see him rather than take a risk with whoever happens to be on duty. I've had enough experience with vets to understand that just anyone is not good enough. But I thank Dakski for the suggestion.
And I want to thank you all for your support and advice. The internet can be an ugly place, but this forum is a rare gem of friendship and comfort.
Finally, I want to stop posting on this thread. The title is too optimistic for the current circumstances and it stabs at me. I'll start a new thread tomorrow, or perhaps the day after so that I can keep you all abreast of the situation as it develops. Of course, I'll stay subscribed so I can read your comments.
Again, you all have my deepest gratitude.
