Susceptibility to illness

Respiratory Tract Infections. Generally related to improper environmental conditions (too cold, wet, prolonged stress - provision of thermal gradient absent in enclosure).

Signs of Illness & Stress in Reptiles:

Lethargy;  Failure to eat over several weeks;  Regurgitation;  Prolonged soaking in water (may be indicative of parasite infection);  Aggression (if, normally, a passive species);  Prolonged gaping (open mouth);  Loss of muscle tone/strength;  Tremors;  Abcess/blisters/scabs.


The Asian rat snake (with the exception of the friesei) are not commonly available.

Look for an animal with a well developed body, no visible cuts or abrasions, clear alert eyes, tongue flicking, no signs of mites or ticks (usually seen in water dish in enclosure), no discharge from the mouth, clean vent.


These snakes are extremely agile & are excellent climbers. The provision of branches or doweling in the enclosure is required. A typical rat snake with the ability to reach an astounding distance from object to object.

Handling of the snake is desirable at an early age to encourage a positive response to touch. Allow 2 - 3 days post feeding prior to handling.

Distress caused if left alone

A snake is a solitary animal by nature.

Refer: Corn snake care sheet.

Ease of transportation


Provide a large ‘fun bin’, Contico box, Faunarium or some such suitable container (with air holes & locking handles) to transport your pet. The use of cloth bags (pillow cases) can cause more stress to the animal whilst being transported.

How we keep our pets can affect our own health.


General removal of debris (food, feaces, urates, blood, saliva etc) which helps reduce the amount of organic matter that contributes to the proliferation of bacteria & disease.

The best method is with hot, soapy water.  Followed by a clean rinse which flushes any loose debris away.  Complete rinse out by use of sponges, cloths or paper towels.

To disinfect (use as manufacturer advises on product), generously apply solution to the  clean surfaces with a saturated cloth, sponge or spray bottle.  Leave for 10 minutes ( 15 - 20 is better).

To sterilize - leave solution for 30 minutes (check instructions on product dilution ratio).

Rinse out thoughly prior to re-introducing reptile to vivarium.

N.B.  Never mix Ammonia & Bleach.  If using bleach to disinfect utensils, sink, water bowls.  Carefully rinse all soap residue as many dishwashing soaps contain ammonia.

A separate set of cleaning equipment should be allocated for animal/reptile use.

Do not use soaps or cleaners which are abrassive, contain pine scents or phenols.

Reptile disinfectants can be purchased through animal supply catalogues or pet stores.

Always instruct children to wash their hands after touching animals or reptiles.
