Garter Snake Habitat
Terrarium is the name given to a dry place used to house reptiles. The terrarium that would be used to condition the snakes could be an old aquarium with a cover in the upper part made out of a smooth weaving net which permits the ventilation but does not allow the snakes to escape. Snakes are very good escape artists; they can crawl through openings that seem too small for them. For that reason the cage must be absolutely escape-proof. Lids should be securely attached and fit tightly: snakes are strong enough to push them off otherwise. Any mesh or grille in the lid should be small enough: if a snake can work its way in past its eyes, it can get all the way out.
The measures of the terrarium should be as follows to allow ample room for your garter snake to roam: 70 inches in length, 13 inches high and 13 inches wide. A substrate kitchen paper shows to be an excellent material since it is very absorbent and smooth.
You might put a thick branch for your snake to coil around and relax and a few rocks (the size of your fist) would be an ideal addition to your snake home as well.
