(eg. description of the frequency and severity of the symptoms
On an unspecified date post application, in 2016, the cat exhibited an unspecified behavior change and was examined by a veterinarian. The cat positive test result for cytauxzoonosis and unknown treatments were performed. On 25Aug2016, the cat died and no necropsy was performed. Due to the sensitive nature of the communication, specific relevant event details were not obtained, nor will such be sought. The reason for the initial phone call was to discuss the use of the product and not to report the death of the patient. No more information is expected. This case is closed.
Death
In this case, no ticks seen on dog. In case of attachment of ticks these will be killed and fall off the host within 24 to 48 hours after infestation without having had a blood meal, as a rule. However, attachment of single ticks and even sucking of blood and thus transfer of tick borne diseases cannot be excluded while the collar is worn and simply reflects the labeled claim of efficacy that is not 100% against ticks especially when infestation pressure is high. Thus, infection with tick borne diseases despite wearing a collar can occur exceptionally and is consistent with the products claimed efficacy. This issue is addressed in the product information. Reported behavioural change is unspecific sign, however in this case, sign likely consequence of later diagnosed cytauxzoonosis. Death is not expected following appropriate topical product application as inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause serious sign. 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. No signs of anaphylaxis reported which would have occurred in close proximity to the collar application. Moreover, the reason for the initial phone call was to discuss the use of the product and not to report the death of the patient. Even though some information is not available (necropsy report and time to onset), sufficient information exists to rule out product relation completely. Finally, a product relation is considered as unlikely.
