Few reports indicate that pets may be exposed to the virus. The present report describes a cat suffering from severe respiratory distress and thrombocytopenia living with a family with several members affected by COVID-19. Clinical signs of the cat prompted humanitarian euthanasia and a detailed postmortem investigation to assess whether a COVID-19−like disease was causing the condition. Necropsy results showed the animal suffered from feline hypertrophic cardiomyopathy and severe pulmonary edema and thrombosis. SARS-CoV-2 RNA was only detected in nasal swab, nasal turbinates, and mesenteric lymph node, but no evidence of histopathological lesions compatible with a viral infection were detected. The cat seroconverted against SARS-CoV-2, further evidencing a productive infection in this animal. We conclude that the animal had a subclinical SARS-CoV-2 infection concomitant to an unrelated cardiomyopathy that led to euthanasia. We appreciate the collaboration of Esther Zamora, Carla Zamora, and their relatives, the owners of Negrito (C1) and Whisky (C2). We also thank Mónica Pérez from IRTA-CReSA for the histopathology laboratory work, and M. Pilar Armengol and the translational genomics platform team at the Institut de Recerca Germans Trias i Pujol for the sequencing studies.
