Referrals only

The Cat Company only accepts patients who have been referred by a veterinarian. We do not compete with your vet. We are a specialized service that complements your vet’s practice.

Your vet’s input is vital in the final decision to proceed with therapy. If the provided information indicates health-related problems that may preclude or complicate therapy, we will contact the referring veterinarian to discuss these issues.

Feline hyperthyroidism is a disorder that occurs when the thyroid gland produces too much thyroid hormone. In most cases, about 97% to 98% of the disease is caused by a benign tumor in the thyroid gland that is not responsive to the normal ‘on and off’ switches that control thyroid function.

Information needed

From your veterinarian

To evaluate your cat’s condition, we will need the following information from your veterinarian.

  • Complete Blood Count (CBC)
  • Urinalysis, especially specific gravity
  • Complete chemistry/electrolyte panel
  • Size of the thyroid nodule, if palpable
  • Total T4

Laboratory studies and other evaluations may be performed up to four weeks prior to admission. The Cat Company may suggest other tests if felt needed.
