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

On December 11, 2016 the cat developed vomiting. Between December 12, 2016 and December 13, 2016 the cat developed anorexia and lethargy. On December 14, 2016 the owner took the cat to the veterinarian (where an anti-emetic, an appetite stimulant, and subcutaneous fluids were given, and blood work was done). On December 15, 2016 the owner took the cat back to the veterinarian where IV fluids were given and the veterinarian indicated they would implement force feeding if deemed necessary. Later that morning the owner contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated s-methoprene has a wide margin of safety. The APSS veterinarian also stated drooling could be seen as a taste reaction. The APSS veterinarian additionally stated the severity and duration of these signs do not fit with an exposure to this product, there could possibly be something else going on with the cat. The APSS assistant recommended having the attending veterinarian call for information (for recommendations and to discuss the questions about s-methoprene).

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. On December 20, 2016 the attending veterinarian called the APSS to discuss the case. The attending veterinarian stated the cat's vomiting ended on December 13, 2016, but the cat developed weight loss (1.1 pounds). That same day, the cat was bathed. On December 14, 2016 the cat started vomiting again. On December 15, 2016 the attending veterinarian performed a barium series, where it was discovered the cat had a hairball which was causing a foreign body obstruction (FBO), and dry feces. On December 16, 2016 the attending veterinarian performed surgery to remove the FBO (hairball). On December 17, 2016 the attending veterinarian did an enema on the cat. On December 20, 2016 the cat fully recovered.
