'''Nutritional''' secondary HPT can affect '''horses of all breeds and ages''' that are either supplemented with large amounts of grain based concentrates or bran, or those that escape and break into a grain store or similar. It is also seen '''occasionally in dogs and cats fed all meat diets and pigs fed unsupplemented cereal''' feed. It is most commonly seen in '''young growing animals.'''

Any disease in ruminants is very rare and usually mild.

Animals affected by secondary renal HPT may exhibit '''classical signs of renal insufficiency such as polydipsia, polyuria, weight loss, vomiting and dehydration'''.

'''[[Metabolic Bone Disease]] in reptiles is caused by inadequate UVB light''' which diminishes '''Vitamin D production''' in the skin. Affected animals often have '''limb deformities, pathological fractures, are lethargic, very weak and inappetant and may also show signs of concurrent [[Hypocalcaemia|hypocalcaemia]]'''. They may also exhibit '''[[Dysecdysis|dysecdysis]].'''

'''[[Metabolic Bone Disease]] in reptiles is caused by inadequate UVB light''' which diminishes '''Vitamin D production''' in the skin. In small mammals it is usually a straightforward dietary deficiency. Affected animals often have '''limb deformities, pathological fractures, are lethargic, very weak and inappetant and may also show signs of concurrent [[Hypocalcaemia|hypocalcaemia]]'''. They may also exhibit '''[[Dysecdysis|dysecdysis]].''' Rodents may have loose or deformed teeth and faces.
