Symptoms & types

Symptoms of hyperparathyroidism in cats include: constipation, poor appetite, lethargy, muscle tremors, excessive thirst, excessive urination, bloody urine.

Understanding the diagnostics

Learning about the causes

Cats who have too much parathyroid hormone will release calcium from their bones and absorb calcium from their guts, making their blood calcium levels too high.

Best treatment options

Home remedies and their effectiveness

Surgery is the best treatment option as it is usually curative. Medication can be used to lower calcium levels, but these are not often used long term.
