Cohabitation: When It Works and When It Doesn't
Most snakes are solitary. Some lizards aren't. The honest version of the cohab debate.
Cohabitation — housing two or more animals together — is one of the hobby's most contested topics, and most of the heat comes from generalizing across very different animals. The honest answer is: it depends entirely on the species and the individual.
Most snakes: solitary by default
The large majority of commonly-kept snakes are solitary in the wild and gain nothing from company in captivity. Co-housing them introduces real risks: feeding-response cannibalism, competition for the single best basking spot, hidden stress, and the impossibility of monitoring individual feeding, weight, and health. For these animals the default is one snake, one enclosure.
Where it can work
Some social lizards and a handful of species tolerate or even benefit from group housing — but only with deliberate conditions: ample space, multiple basking and hide options to defuse competition, careful sex ratios, and constant observation for bullying. Cohab done right is more work and more space, not less.
