On approximately 29-Jun-2019, the cat developed excessive thirst. On approximately 05-Jul-2019, the cat developed weight loss. On 11-Jul-2019, the cat developed an abnormal body odor and nasal discharge. On 12-Jul-2019, the cat was evaluated by a veterinarian weighed 7 pounds. Unspecified blood work was performed and the cat was diagnosed with decreased kidney function and a bladder infection. Intravenous fluids and unspecified antibiotics were administered and continued to be administered to the cat. The cat continued to be hospitalized and the clinical signs continued unchanged. Follow up received on 2 Aug 2019: The cat continued to be hospitalized and the clinical signs continued unchanged. On an unknown date in Jul 2019, the cat was re-evaluated by a veterinarian and hospitalized and released after 3 days. The clinical signs continued. On 28 Jul 2019, the cat was re-evaluated by a veterinarian and administered an unspecified amount of injectable fluids. On 29 Jul 2019, the cat was re-evaluated by a veterinarian; the owner elected to humanely euthanize the cat. No known necropsy was performed. No more information is expected. This case is closed.

19. Provide supplemental information here

O - Unclassifiable/unassessable Excessive thirst is unspecific sign and may have other numerous causes. Malodor after topical product administration is not anticipated. Apart from that, the bad smell on administration of product is subjective to the individual concerned. Malodor may have multiple other causes (e.g. diet, humidity, fur condition) and is rather connected with the animal than the product. Reported weight loss, nasal discharged, diagnosed decreased kidney function, bladder infection and need for death by euthanasia are not expected with use of product as inconsistent with the pharmaco-toxicological product profile. Product has wide margin of safety. Oral LD50 in rat is 642 mg/kg BW. 24-fold overdosage tolerated by cats without showing any side effect. Other unrelated causes must be considered in this geriatric animal. Time to onset is short for initial reported systemic sign but long for later reported signs. Overall, a relation to this case is considered as unassessable.
