- Brumation
- A winter rest of 10–14 weeks at 5–10 °C — without it there is no breeding and a markedly shorter life
- Cohabitation
- Group housing is possible, since studies show the species is polygynandrous with heavily overlapping home ranges and high population densities — strictly mutually exclusive male territoriality, as the standard template assumes, is not documented to the same degree. Still give each animal enough basking and hiding spots.
