Bests & Worsts Reviews from Amazon

This product is probably made in China. Every time I try to get an answer out of this company of where this product is manufactured- they lie and give me a state- no address- just a state. I research with the FDA ,(as it says on the bottle they are FDA inspected) there is no such mfg in that state that the FDA inspects. Also- they they they are vet formulated. Which Vet? They won't answer that question either. Also- the Portland OR address on the bottle is a distribution center.
