Query: Cat Echinacea/Goldenseal tincture

Hi ... I recently purchased Animals' Apawthecary Echinacea/Goldenseal Blend for pets. I have used this before to boost my cats' immune system. It is an excellent brand! I purchased on-line from Spring Valley Herbs via Amazon. Their price is great including shipping and I would recommend them. The first order showed that it was delivered by the USPS but for whatever reason, it was not located. They replaced it within a week or so without charging me and I received the replacement quickly after it was sent. I will definitely purchase from them again!
