[EX Q]: Very high quality dulce de leche from Argentina. Compared to most brands, it's a bit lighter colored, and the taste is more subdued and milkier. You may or may not appreciate this, as it's not the classic taste that you expect from commercial dulce de leche, but it's by far the closest to the homemade dulce that my grandma used to make. For this, I'd give it 6 stars if I could!
[EX A]: Positive

[EX Q]: The name of this coffee is Mahogany, in my mind a deep rich brown. The coffee flavor is deep and rich, and the color is dark brown. It is delicious.
[EX A]: Positive

[EX Q]: Many people are buying this food believing it is safer because it is made in New Zealand. It is now made in the US by Performance Pet Products. I have been feeding this food to my cats since the recall horror of 2007 and prior to the change it was excellent food and I was thrilled with it. Since ZiwiPeak has been switched to canning in the US it has been a nightmare. Several times in the last year I have opened the food to find it is a green or blue colour. I had to return those cans because it made both my cats vomit and have loose stools. Also recently I have found large sharp bone pieces are present and very large strange chunks of greyish pink material that looks like connective tissue. I've contacted the US distributor twice but they have never replied. A batch I got this month with an expiry date of 2014 has caused severe vomiting and shedding with both cats who were previously healthy.
[EX A]:
Negative
