19. Provide supplemental information here

B - Possible - Off-label Use (unauthorized species). Reported dyspnoea is not expected with appropriate topical product use. It may rather be a behavioural reaction to product sensation than a sign of respiratory illness. Further reported tremors and ataxia are consistent with permethrin toxicity following direct product use on a cat. Pyrexia may be associated with excessive muscle activity. Head shaking is an unspecific sign. However, it may be associated with reported neurological signs. Considering consistent time to onset, a product connection is deemed to be possible.
