I kept Kansas Glossies and found them to be easy. Mine were kept on sand with very limited water. They acted like sand boas, staying under most of the time, and ate mice readily as long as they were small.
Temp was not an issue. I had no AC and in Florida that means temps to the 90's. Did not seem to matter as they never stopped eating.
Foos size I found, is part of the secret to success. Being very lizard orriented, their underslung mouth makes it hard for them to eat the same size prey a ratsnake of similar size will.
Mine bred producing 7 eggs which hatched in 44 days. After their first shed all seven ate live NBP.s without any encouragement.
