Excellent probiotic, I give it daily to my cat upon the recommendation of my vet to prevent eye infections as she is prone to them. Since taking this probiotic, she hasn’t had any and she loves the taste. Prior to taking this probiotic she had two eye infections within 6 months ( she is only 1 year and 4 months old). I highly recommend this probiotic and I received excellent service from the Cascade veterinary hospital, excellent price and fast shipping.
