International CatCare (iCCare) and the International Society of Feline Medicine (ISFM) have embraced the worldwide concerns being raised about parasiticides used on pets and how they can contaminate waterways. That, of course, has far-reaching implications for they may affect wildlife. In response to the waterway concerns, the organizations have released a joint statement with recommendations for the cat owner:
Bathing cats is not necessary (unless for a specific medical problem).
Apply topical parasiticides correctly.
Where topical parasiticides are used, covering the cat’s bedding with a disposable cover until the medication is dry reduces the risk of parasiticides getting into the wastewater when the bedding is washed.
As some parasiticides may be excreted in the cat’s urine or feces, dispose of litter appropriately in rubbish bins to avoid wastewater contamination. Providing outdoor toilet areas away from water courses in a garden also helps reduce the risk of contamination.
Seek advice from a veterinarian to assess each cat’s risk and need for parasite control rather than using over-the-counter products.
