Q: My cat and my neighbor's cats would not eat this food. I wound up giving the case to the cat rescue organization.

A: Negative
****
Q: I cannot get my dog to use this no matter how hard I try.  My dog is the most food motivated dog I've ever known.  She will do ANYTHING for carrots, lettuce, ice cubes... even her own kibble.  But regardless of what I put in this thing, I cannot get her interested in this toy to save either of our lives.  I even tried clicker training her on it!  She doesn't associate it with food no matter what I do.

A: Negative
****
Q: These are the strongest tasting salt and vinegar chips I've had.  I could still do with more vinegar flavor, but I think this is as close as I'm going to get without dousing them with vinegar powder myself.  I did a side by side with the Cape Cod salt and vinegar and these are about twice as flavorful.  Additionally, as other reviewers have said, they have quite a good bit of potassium in them (somewhere in the neighbor of 15% RDA per serving).

A:
Positive
