Was taking my 7 month old kitten to the vet to have her stitches removed from her spaying a couple of weeks ago. I really wanted her to be able to go outside and be able to playmand explore – we have a large backyard in a very quiet cul-de-sac. I picked up the Hartz UltraGuard OneSpot drops for cats and applied it behind her shoulders as the directions said. The trip to the vet for the suture removal was next on my list and that was a fortunate thing! Within 20 minutes, she was drooling, foaming at the mouth, and otherwise very distressed. The vet gave her a very thorough cleaning and fortunately, she seems to be ok. I was furious that a company could sell this product without proper warning of the potential risks involved. All they have is some vague, generic warning about sensitivities to pesticides. I am very fortunate that Tigerlily is ok, but I am out $50 for the emergency wash/cleaning. I wrote a letter to Hartz describing the ordeal, but I am not holding my breath for a response. Has anyone else here had success getting reimbursed for vet bills, ect? My heart goes out to all of you that lost a beloved pet from this poison.
