As for specific regarding your pregnancy, it has been my understanding that there are times that are more sensitive than others during your pregnancy, for example the first 4 or so months are really focused on developing the babies systems so contracting something during those times is more risky in terms of developmental effects, vs later on in the pregnancy when a lot of the systems have developed at least somewhat and the baby shifts more into growth/weight gain mode. A lot of pregnancy books go into this in detail of what develops when and what would be considered more risky during those specific times of development. I would say get a good book a look into it because my 'baby' is almost 5 so my memory is somewhat fading concerning the specifics.
I would think that if you wash your hands and that sort of thing you should be fine. If you where really concerned you could consider wearing gloves to handle the snake or while cleaning its cage, just while you are pregnant. But even if you do wear gloves wash you hands/arms afterwards. Or if someone else can help with cage cleaning while you are pregnant that might help. My husband had litter box duty when I was pregnant, I considered it to be an even trade because I was so queasy all the time so it was sort of like his penance LOL. My advice as a 2 time mom would be to read a lot about your pregnancy, but to take all the scary things with lots of grains of salt. Being healthy, informed, and careful is important, but there is also a lot of hype and hysterics in the parenting world. It is really hard sometimes to tune out some of it especially with your first baby (I was a worrier for sure and am totally guilty of falling for a lot of it), but it is the sort of thing you learn to recognize with time.
Oh and congratulations and non queasy wishes!!
Congrats on the pregnancy!
