A few months ago I bought an albino coastal rosy boa from petco. It was young and a very mean snake that struck everytime my hand entered its cage. I noticed at the store it had a few mites, so they gave me some vet medicine to spray on him. The spray seemed to be as affective as tap water so ten days later I returned him. I went to another pet store and got my first ball, Im glad I did balls are great. I went back to petco yesterday and asked "hey what ever happened to those rosy boas" the guy told me the mites got even worse and had to send them out to antoher vet. Inspect your animals carefully before puchasing. Take them to good lighting or outside, its important having an infested animal is not fun
