|In the following lines I describe my keeping of the animals in my own "German way". Here we have legislations for keeping reptiles wich collide with the "American way" of keeping them in (small) plastic boxes in a tray. Thus I must say, that the keeping in those boxes is a good way to keep a lot of Pituophis stress free.
There are allways several ways for the same aim: Keeping them healthy and in a good enclosure - and breed them.
Expectaly the animals of the melanoleucus-group and the sayi regulary reach 2m in lengh. So they need a larger terrarium with some stable hiding places. Smaller subspecies and specimen need less space. Klimbing branches and some klimbing help on back- and sidewall of the terraria should be offered for the most snakes. The greater Pituophis have a great appetit and can make great piles of shit... Because of this the ground gravel should be absorbent. One of the many sorts of possible gravel ist pressed straw (for rodents or cats) or cocogravel. Other substrates inclusive newspapers are useful, too.
With a waterbowl there will be automaticly an air humidity at aprox. 40-60%. With this the animals live good, further water I spray only in the sheding phase. The gravel stay dry. The prefered temperatures of the Pituophis are below 30°C, warmer places are only visited after feedig or for warming up in the morning. Permanent temperatures a little above 30 °C many subspecies tolerate, but with rising temperatur the animals become nervous. The actual place in the terrarium and the klimbing needing is connect to the accuring temperatures. For warming up they mostly are in warmer and higher places. Have they reached the preferd body temperatur, they go to the ground and stay there. Too, the need of a bath is connect to the temperatur: If it become too warm in the terrarium, they more often go into the waterbowl for cooling.
Each terrarium is illuminated with an 18 W-illuminating tube lamp or a 5-9 W energie saving bulb. The illumination time in summer is 14 h.
Most of the Pituophis can live good together in groups of 2 or 3. But there are exeptions: Some induviduals "don't like" the partner, wich I give them. If I can't give each a own terraria, I bring more hidingplaces in. This helps in most times. Otherwise the more stressed animal don't like to eat or refuse the food. So it can become ill and must be seperated immediatly. With snakes of other taxa they can live together, too.
