Feline hyperthyroidism occurs in about 10% of cats over 10 years old.  It’s caused by an overactive thyroid gland. Pet parents of cats with hyperthyroidism report the following symptoms:

• Increased vocalization

• Vomiting or Diarrhea

• Increased water intake

• Increased urination

• Weight loss despite a normal appetite

• Restlessness, increased activity

• Defecation outside the litter box

• Poor grooming

Early diagnosis by blood screening is key.  From there depending on symptoms, treatment is less complicated with early intervention.
