11July2011 owner applied Advantage II Large Cat to Gabrielle a 9 year old male Domestic Shorthair that weighs 14 pounds for flea infestation. Less then 8 hours after application this feline lethargic. On 14July2011 this feline was not willing to walk. Veterinary examination this cat presented at the clinic with white / pale mucous membranes, body temperature of 94.8 degrees, obese according to the doctor. This feline weighed 14.8 pounds and should have weighed about 11 pounds. That was the first time this doctor had seen this feline. This feline died during the examination process. The DVM drew blood (which was very thin) and sent it out - a CBC and path report are pending. The doctor wants to rule out a flea-borne disease. No necropsy was preformed.

19. Provide supplemental information here

Lethargy may exceptionally occur in particular sensitive animals. Other signs not expected after topical product application as inconsistent with pharmaco-toxicological product profile. Onset time of 3 days for other signs, argues against anaphylactic reaction. Lab results indicate also other cause, see low values for almost all parameters. Samples negative for mycoplasma. However, product relation furtheron considered unlikely.
