The owner applied the Advantage II for Large Cats to the cat on 7/18/11. On 7/19/11 the cat seemed stiff in the rear legs and was knucking over on the left front leg. The cat is currently at the veterinary clinic being examined, however no treatments have been done at this point. The veterinarian did say that the exact same thing occured last month 1 day after the application. The cat was treated with dexamethasone and radiographs were done with no significant findings. The cat recovered within 1 weeks time. 23.05.2012: On approximately 26 July 2011 the cat developed paralysis of all four legs and could not urinate on his own. The cat was hospitalized at the clinic daily and had his bladder expressed twice a day until 22 May 2012 when the cat seemed to have a stroke and pass away.

19. Provide supplemental information here

Originally reported signs -'Neurological signs NOS' and 'Stiff gait' are not typically observed with appropriate topical product administration. An appropriate dosage was applied and no oral product uptake reported. Update information concerning clinical course not reliable. Paralysis, stroke and finally fatal outcome 10 months after product application indicate other cause for signs. Overall, product relation considered unlikely.
