Also Known As: '''''Yellow Fat Disease'''''
==Introduction==
'''Steatitis''' is also known as ''''yellow fat disease''''. It occurs in many species including cats, reptiles and mink. It is not seen in ruminants.
The condition occurs in animals fed on a '''fat-laden diet''',''' high in polyunsaturated fat and low in tocopherols'''. This causes an '''[[Inflammation|inflammatory response]]''' of '''adipose tissue''' due to '''oxidative damage'''. [[Vitamin E Deficiency|Vitamin E deficiency]] is thought to contribute to the condition.
==Clinical Signs==
The animal normally presents with '''firm nodules in subcutaneous tissue''' that are '''yellow or orange in colour'''. Mink may also present with abnormal locomotion and sudden death.
==Treatment & Prevention==
The condition is '''vitamin E responsive''', therefore affected animals should be treated with oral or injectable vitamin E supplementation and fed on a '''low fat diet'''.
The condition is prevented by feeding an '''appropriate diet''' (low in polyunsaturated fat) and supplementing the diet with '''vitamin E'''.
==Prognosis==
If the condition is recognised when the signs are mild, then prognosis is good - with complete reversal of signs. More chronic lesions are harder to treat as they may be walled off by a dense capsule of fibrocollagenous [[Connective Tissue Histology resource|connective tissue]].
