I do agree, however sometimes when snakes get sick they will not get better with any medicine. Many times they will go off food and they will slowly wither away, and I mean slowly. Some snakes can take a long time to go through their fat reserves.
At the end of the day, it matters what the sickness is and what have you done to try to fix it. The effective but oft over prescribed Baytril isn't the end all be all of medicine, and many times it take culture sensitivity tests run by your vet to figure out just what is going on .
