We have had numerous cats who have been in intensive care with the Hartz® otc product.
Owners need to be aware that virtually ALL of the over-the-counter products (not just Hartz®) contain permethrins or pyrethrin derivatives.
This is a 30 year old technology design and packaged to copy the modern flea product like Advantage®, Top Spot® and Revolution® available only by prescription through veterinarians.
These products are dangerous and life threatening to cats and we had one cat die from the product.
The new products available through your Vet are safe and effective, but you must establish a Doctor patient relationship in order to purchase them.
Revolution® is the newest product out. We use a lot of it, particularly on cats because it will kill flea, ear mites, internal parasites (except tapeworms) as well as function as an effective heartworm preventative.
Contact your Vet and get ahold of the new products as they are safe and effective.
