ABSTRACT
OBJECTIVE: To describe the clinical course and novel biochemical changes in 3 cats with lisdexamfetamine (LDX) toxicosis. SERIES SUMMARY: Three cats presented with LDX exposure and initially displayed typical clinical signs of amphetamine toxicosis. However, over the course of hospitalization, hypoglycemia and markedly elevated creatine kinase levels consistent with rhabdomyolysis ensued. All cats were treated with sedatives including phenothiazines and dexmedetomidine. Two cats were hospitalized for 4 days and 1 for 5 days. All cats survived. NEW OR UNIQUE INFORMATION PROVIDED: This is the first case series in cats that reports the novel biochemical changes of delayed hypoglycemia and elevated creatine kinase several days into hospitalization for the treatment of LDX toxicity. The development of delayed clinical signs suggests reconsideration of established hospitalization guidelines for amphetamine ingestion in cats.

Three dogs that presented to the emergency service in severely emaciated body conditions were admitted to the hospital for monitoring and refeeding. During their hospitalization, all three dogs developed electrolyte derangements or required supplementation to prevent hypophosphatemia and hypomagnesemia. Additionally, all dogs developed hyperlactatemia, which was suspected to be secondary to thiamine deficiency. Two dogs were reported to have cardiac abnormalities, including cardiac arrhythmias, systolic dysfunction, and spontaneous echogenic contrast. These cases highlight the complexity of refeeding syndrome and its associated complications that extend beyond electrolyte deficiencies.
