Used for less then 2 months both cats fur began falling out bad. Stopped using it & the cats fur is back to fine. Back to feeding my cats Nature's Variety instinct. I baught this PetGaurd product at Fairway Market not Amazon. Will not use it again.
Cat Loved it.. BUT....Their hair started to fall out.

I have tried various brands of stevia, but I always come back to NuNaturals.  I buy the 12 ounce container because I use it to sweeten everything.  If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you.  I drink a lot of tea, and this is my sweetener.  A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem.  Highly recommended.

Great Taste and Zero Calories
