18. Severity classification (if there is more than 1 possible classification


19. Provide supplemental information here

N-Unlikely: Reported signs like increased urination, mammary lumps, heart arrhythmia, kidney disorder, inability to jump and serious sign such as death are not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause these 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. Anmal involved in this case was geriatric. Moreover, previous applications were well tolerated. Other causes are more probable. Considering long time to onset, a product relation is considered unlikely.
