We Pity The Kitties concerns

[faycat]

Some time very shortly after I first adopted my kitty Opaw, I started giving her We Pity The Kitties Alaskan salmon cat treats, made by Three Dog Bakery.  They are supposed to be 100% pure freeze-dried wild Alaskan salmon and nothing else, so I figured they were as good as a cat treat could get.  She was totally obsessed with them.  Opaw had problems with regular vomitting as long as I can remember (she is now 4 years old), and the vet had tested her for everything we could think of, and I changed her food a couple of times in an attempt to isolate an allergen and get the best possible quality food for her.  Nothing worked.  But recently when the pet food recall started, I realized that a little sticker on the pouches of these salmon cat treats said "Product of China".  I immediately stopped giving them to her, and now only give Halo Liv-a-littles chicken or cod fish treats.  Since I stopped giving her We Pity The Kitties treats, she has not had another instance of vomitting.  It has been over 2 months, and she used to vomit almost every week.  I feel like I have to draw the probable conclusion that perhaps those treats were not what they were supposed to be. 

Does anyone else feed their cats these treats?  Has anyone else had problems with their cats vomitting too frequently?  The concern was when she vomitted small amounts of yellowish foam, not regurgitated food (which is pretty normal for some cats here and there).  For what it's worth, I can't be completely sure how soon after I adopted her she started the regular vomitting, but it was pretty soon.  And I'm pretty sure I found those treats within a few months of taking her home.
