I have a 6 year old cat who likes to sit outdoors on our deck. As a precaution I administered Hartz flea and tick, exactly as the box as prescribed. I’ve used this exact one just last year with no problem. However, this year, within 20 mins- she was foaming at the mouth and running around like a crazy cat. I immediately googled and came across this page…. I gave her a bath, with my baby’s shampoo , as it was the only sensitive thing I had on hand.-within 30 mins of the administration and she seems to be acting a little better now…. I’m keeping my fingers crossed. How is this stuff legal? I’m outraged!
