My Russian blue cat has always had really healthy food I decided to feed her a lickable treat stew by the Hartz mountain product corporation it says it’s for seniors 10 years plus with vitamin C and B chicken tuna flavor. My cat immediately became ill threw up for three days Until she was only throwing up yellow bile,and would not eat. After a visit to the vet $749 later the vet decided it had to be the food as nothing else was wrong with her. I am extremely upset that these products are allowed to be on the market. If you had the same experience please post your story. In my opinion this company owes me a vet bill. I will post on every site I can find as this is an unacceptable situation and should not of happened to my poor female cat.
