as a fogger to ensure any beginning stages of RI are taken care of as a preventative there has been a large outbreak of RI in my area there is one pet store that was completely wiped out the one I got my pythons from to be exact we had one of our pythons die from it despite all efforts and I want to prevent any beginning stages because this strand is taking less than 72 hours to kills from initial signs the vet here took cultures and is having them analyzed but it apperently is a very strong and nasty strain
