[EX Q]: I ordered this saffron after looking at seller feedback and assumed that since this is expensive it will be premium quality. But only after i put it in water for sometime, then the color of the flakes changed, and I realized that its a fake one. Dont waste your time on this.
[EX A]: Negative

[EX Q]: This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!
[EX A]: Negative

[EX Q]: I usually make my baby's food.... it's so easy, steam fruits & veggies and puree.... but sometimes I don't have enough time to cook and I buy Earth's Best baby foods....baby likes all the fruits and veggies so far but didn't like this one. She refused to eat it. When I tried it I understood why, I wouldn't eat it myself either... it tastes nasty.... my poor baby.... immediately I made her a homemade potato, zucchini, & asparagus puree and she loved it. I wouldn't recommend this flavor!
