Bests & Worsts Reviews from Amazon

I bought this for my mom's cat that loves catnip. My mom says that her cat not only did not like it, she "recoiled" from it. Those were her words as I did not witness it but I figured Hmmm, weird, let me try it on my cat, who also loves catnip. Well, my cat sniffed it a little but really had almost no reaction to it at all. She usually grows crazy for it! So definitely something wrong with this product, I thought. Later, however, I saw that my cat was eating it, and almost all of the catnip that I had placed on the tile floor was now gone. I know some cats eat catnip but my cat had never eaten it. She became very ill within the next 2 days. She was a 4 year old indoor cat and had never been sick even a single day. Don't remember her ever even throwing up. I took her to the vet and they said her kidneys were failing, likely due to ingesting something toxic. They mentioned antifreeze and some plants but my cat is indoor and doesn't have access to anything like that. My cat was gone four days later despite my best efforts and full 24-hour emergency room vet monitoring. I have no proof that this catnip made her sick and so I debated even posting this information, but in the end I felt it was important. What if this product is toxic to some cats? What if their quality control is so poor that some of their containers have worthless or toxic contents? This is the first bad review I have ever posted so please believe I am taking this seriously. If anyone has had a similar experience with this catnip, please post on here.
