Thanks! I didn't realize the AB's would still be working for a little while after the final shot.
The thing that surprised me was that he got the RI in the first place. Our temps and humidity are checked several times a day and have been great! I am a stay-at-home mom, that's why we can check the temps/humidity so often. The vet said that sometimes a mouse/rat can have bacteria and the snake could have picked it up from them.
