Garter snakes are surprisingly simple to care for in captivity.
They require a reasonably-sized cage because they are quite active snakes. A cage measuring 60cm x 30 cm
will easily house two or three specimens and in general they will live happily together for life.
This cage should be heated at one end to a temperature of around 25 - 28'C which will suit garter snakes
right through the year.
Being quite a shy snake, when caring for garter snakes it is important to include a number of places to hide.
Curved bark, small pieces of wood, rocks and custom-bought hides will all the job, as will some artificial
plant matter if it is dense enough.
If using the heavier materials - such as rocks and slate - it is adviseable to use aquarium sealant to glue the hide
into place so your garter snakes can't disturb them and so risk crushing themselves.
The base of the cage should be lined with a suitable reptile-safe substrate of which bark shippings (sometimes
known simply as "forest" or "rainforest" substrate) does an admirable jobin this department.
I also like to add some moss, leaves, bark and other items found in my local forest to make it look more realistic though
this is by no means essential.
Water should be available at all times for your garter snakes to drink and/or bathe in.
Garter snakes should ideally be fed once or twice a week. With their active lifestyle they can get through quite a few calories and
for growing youngsters the more frequent feeding pattern is strongly recommended.
The diet when caring for garter snakes is discussed fully here.
Besides feeding, and daily changing og the water to keep it fresh, another regular task worth carrying out is
a cage check once week or so.
Check it over the ensure the heating and lighting is working as they are supposed to - that the cage isn't too warm or too cold for example.
Also check that there are no gaps in the cage that have appeared which may enable your snakes to escape.
As tends tend only to defecate a few times a week, they only need cleaning thoroughly a few times a year.
Of course, for this to work you need to remove these movements as soon as they are produced, and any uneaten food should be removed in a timely fashion.
If this is done, a thorough clean of the cage should only be needed every 2 - 3 months.
However, if you leave until this interval, ensure the cleaning job you do is very thorough.
Remove all the substrate and dispose of it, then use a reptile-safe detergent to clean everything else - water bowl,
the whole cage, hides etc. then wait until they are all bone dry again before setting up the cage once again and
reinstalling the snakes you're caring for.
