N - Unlikely Initially reported systemic signs are unspecific and may have numerous other causes. Even though systemic signs like anorexia, adipsia, lethargy may occur initially after collar administration, dehydration would not be expected. The other signs reported along side such as nasal discharge, dry lips and urinary incontinence too are unexpected with product use. Most likely reported signs were consequences of the later diagnosed renal and hepatic disorder which ultimately culminated in death. The worsened anemia and other abnormalities, though unspecified, were most likely associated with altered renal and hepatic function. Skin infection may have been a consequence of pre-existing irritation, aggravated by the critical condition of the animal. Overall, serious signs involving vital organ systems as well as a fatal outcome are not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause such signs either. An overdose of 5 collars around the neck was investigated in adult cats and dogs for an 8 months period and in 10 week old kittens and 7 week old puppies for a 6 months period without causing serious signs. Further, pre-existing concomitant medical condition of anaemia and weight gain indicate that the later diagnosed conditions may have been pre-existing and were co-incidentally diagnosed after collar application. Moreover, animal was of advanced age and thus pre-disposed to reported medical issues. Even though time to onset is short for the initial reported systemic signs, it is inconsistent for the other reported signs, particularly the serious signs. Considering all the above aspects, product relation is deemed to be unlikely.
