Miscellaneous Conditions

                   ------------------------



RED-BROWN TEARS OF RATS:  Rat owners, at some point, notice

red-brown tears staining the eyelids, nose and sometimes the

front paws of their pet rats.  This substance is always mistaken

for blood.  It is actually a normal secretion from a large gland

behind the eyes.  Red-brown tears are noted most often in

response to stressful situations (restraint, fright, illness,

etc).



CANNIBALISM:  Female rats (mice much less often) disturbed

shortly after giving birth to a litter may destroy the pups and

eat them.  Male rats also engage in the same behavior.  For these

reasons, it is important not to disturb female rodents for 2-3

days after they have given birth.  Male rats must be removed from

enclosures just before females deliver their litters.



SKIN DISEASE:  There are many causes of skin disease in pet mice

and rats.  Numerous infectious agents, including bacteria,

viruses, fungi and parasites, may be involved.  Cage-mates may

be responsible for hair loss and/or wounds to the skin.

Allergies are also a suspected cause of skin disease of pet

rodents.  In these cases, it is wise to replace the bedding

being used with plain white, unscented paper toweling.



A veterinarian should be consulted when pet mice and rats exhibit

signs of skin disease.  The doctor will need to conduct

diagnostic tests.  Appropriate treatment is then based on the

results of these tests.
