#1 - PORPHYRIN
Ever realise the red discharge that looks like blood around your rats' eyes or nose or both? Relax.. It is not blood, but instead it is an organic compound known as porphyrin (pronounced por-fur-in). Porphyrin is produced by the harderian gland located behind the rats' eyes. Porphyrin is like the mucus in our nose but red in colour. Small amount of porphyrin is normally found around the nose of the rat when he first wakes up, or when he sleeps for long period. However, owner must monitor the rat's condition and behaviour to tell what amount of porphyrin is consider as normal discharge. If there is a sudden increase of phophyrin discharge, it means that the rat is having some problem. Stress is one of the reasons a rat will produce excessive amount of porphyrin. Another reason for a rat to produce excessive phophyrin is a rise in body temperature or he is suffering some sort of illness. Although porphyrin does not always mean something is wrong, in many cases it does, and it should never be overlooked.
