We have been asked to share this information with our Club by the GCCF
The GCCF has recently received a report of the sudden death of 2 BSH cats a few hours after being given the recommended dose of a flea treatment containing an insecticide called spinosad. A third cat died suddenly two weeks after dosing and there are internet reports of some dogs and cats experiencing side effects of severe sickness and fits. It is a prescription only medicine and taken by mouth rather than applied to the skin. If you have concerns after reading this please discuss your methods of flea control with your vet.
