Objective. To update concepts related to feline hyperthyroidism. Materials and methods. Information from available literature from the last 50 years including the BBCS-LILACS, Fuente Académica, IB-PsycINFO, IB-SSCI, IB-SciELO, Scopus and Scirus, databases as well as historical articles, texts and references cited in published papers was analyzed. Results. Pertinent information related to the objectives proposed in the present review was obtained and it can be classified in five sections as follows: etiology, physiopathology, clinical signs, diagnosis and management. Conclusion. Feline hyperthyroidism is a disease caused by high levels of circulating T4, T3 or both. It is the most common endocrine disorder in domestic cats and affects approximately 1 in 300 cats showing multisystem complications. Currently, there are both medical and surgical treatments. Medical therapy is a conservative alternative which given the appropriate facilities has an effectiveness of 90%. However, depending on the etiology of the disease, thyroidectomy may be more effective for example in the case of tumors.
