I purchased these little treats as stocking stuffers for our little furry friends.  Both Yorkies LOVED these treats.  We had to finally buy more since they liked them so much.

I had to be taken to the ER in an ambulance earlier, the day before yesterday. I was having seizures, near-syncope (passing out, but still being somewhat conscious), couldn't breathe, and my blood pressure was at stroke level. I felt like and thought I was dying (or maybe already) dead for about 3 hours. It was painful and horrifying. I think I figured out what it was that caused my near-death experience. It was probably the energy-shot I took 20 minutes before then. I don't usually take something like that. Someone offered it to me, and I was so tired, I didn't even look at the bottle and took it. Please, don't use these!

My recommendation? Get a juicer and make your own, or try Odwalla. The taste was bitter, and the smell was strange and foul. The label says "Enriched with organic lemon juice" and that is not pure carrot juice in my book. Maybe it was the lemon I tasted, I don't know. I had about three sips and couldn't stomach it.
