I recently rescued a mother cat and 6 kittens. After finding homes for all of them, I had just mama cat left. I noticed a few fleas on her and treated her with Hartz drops. That was 12 hours ago. She is shaking, vomiting and just miserable. There is not emergency vet in my area. I’m just holding her and trying to keep her comfortable. I am outraged that these companies are allowed to get away with this.
