Length:: 0:06 MinsMy brother and his wife purchased this awful product for their cat, and after applying it as directed, the cat went into convulsions. The cat had to go to the vet, where they sedated it, but now $1200 later the cat will most likely die. They called Sargeant's, and the company said to file a claim and they'll reimburse part of the vet bill, but the vet wouldn't release the cat after the first $450 bill (my brother told them to call if the treatment was "too expensive" because they would consider putting the cat down because they couldn't afford anything excessive), and forced them to keep it over the weekend because they couldn't pay the bill, and then added to it until it was $1200.Watch the heartbreaking video of the cat in convulsions. Amazon needs to pull this product. The product reviews are telling.
