Had to take my 8 yr. old Himalayan cat to the vet yesterday because she is having side effects from the Sergeants Gold. She was given a shot, bath, and an iv. How long can I expect before she's back to normal? Still very concerned and its Saturday so no answer at vets. I will never put an other product on any of my pets with researching them first. I'm appalled that this product is on the shelves if this many pets have had the same reaction! Thank you
