(eg. description of the frequency and severity of the symptoms

On August 5, 2013 the owner noticed that the cat had an isolated episode of drooling. On August 9, 2013 the owner noticed that the cat was inappetent and had lost weight; that day the dog in the home was started on aspirin crushed in his food, and the owner thought it was possible that the cat may have ingested some of it. On August 13, 2013 the owner noticed that the cat was holding his head low, was lethargic, and was urinating on himself. On the morning of August 14, 2013 the owner contacted the Animal Product Safety Service (APSS) to obtain help. During the consultation with the APSS, the owner was asked to evaluate the cat's gum color; the owner observed that the cat's gums and tongue appeared white and gray, instead of their normal pink color. The APSS technician recommended that the owner call back with questions, take the cat to the veterinarian, and have the veterinarian call for information.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation and that aspirin was considered to have a low likelihood of causing the clinical situation. Later on the morning of August 14, 2013 the owner called the APSS to update the case. She stated that shortly after she spoke with the APSS that morning the cat had a seizure and died. The APSS veterinarian recommended that the owner consider pursuing a necropsy and to have her regular veterinarian call for information regarding a necropsy. On August 15, 2013 the owner's regular veterinary staff contacted the APSS to discuss a necropsy and the APSS veterinarian faxed necropsy instructions to the clinic. Later that day an APSS technician contacted the clinic to verify that they had received the necropsy submission forms; the clinic confirmed that they had and that the body had shipped that day. On August 21, 2013 gross necropsy results were received. The results revealed a marked flea infestation and presumptive mild anemia. The report stated that the cause of the cat's death was not apparent upon gross examination, and that a histopathology exam was in progress; results will be filed when they become available. The necropsy results were received on Aug 29 and though they were not able to find a cause of death, the results were suggestive of heart failure.
