I might add that having at the very least a fecal exam be done. (I had 9 rats tested from 3 suppliers and 2 or the 9 had parasites) freezing is not often long enough or cold enough to be certain of 100% kill of all possible parasitic vectors.

I would give serious thought to having a blood screen also done. This can establish a base line of there is some health issues down the road but also will point out many internal organ issues.

I might consider an IBD test. IBD is the one of the most scary things a snake can have. It is very rare in pythons. There is so little known about it that makes it scary. The incubation period is unknown it could be quite long however Dr Jacobson DMV said there is no evidence it kills quickly and could be carried for long periods of time. The vector of transmission is unknown, The speed of death is unknown and the treatment is also unknown. There is a test however for it this can be done by Dr. Jacobson at the university of Florida.

90 days I would consider to be a minimum.
