my cat licked a lot of s-methoprene (Hartz ultra guard one spot) treatment off his back about 3 hrs ago. I called Hartz who said he will be fine, and they test the product for ingestion. They told me to feed him tuna water, which he drank (about a 1/3 cup) or to feed him treats to get the metal taste out of his mouth. They also said he might start foaming at the mouth, but that’s just because cats cant spit & instead they foam. I fed him tuna water, and treats, AND bathed him with dishwashing soap. He doesn’t appear to have any symptoms, and I never saw him foam at the mouth. I am still worried…. any advice?
