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:
Vomiting or Diarrhea
Increased water intake
Weight loss despite a normal appetite
Restlessness, increased activity
Defecation outside the litter box
Early diagnosis by blood screening is key. From there depending on symptoms, treatment is less complicated with early intervention.
