If cardiac disease is suspected (loud murmur, tachycardia HR > 240/min, gallop rhythm, dyspnea), cardiomyopathy should be screened for with chest radiographs, echocardiography (available through www.animalsoundsnw.com) or IDEXX proBNP blood testing prior to referral. Results should be faxed or e-mailed prior to treatment date.

Cats with “apathetic” hyperthyroidism (i.e. anorexic) should also have thoracic and/or abdominal radiographs as well as other indicated diagnostic tests to rule out occult neoplasia or other significant intercurrent illness prior to referral.

NOTE: Cats must be eating and drinking adequately on their own (i.e. no parenteral fluids or assisted feeding while hospitalized). Oral medications or injectable medications are OK during hospitalization.
