Review on 🐱 Optimized Pet Nutrition: VetOne Advita Powder Probiotic Supplement for Cats by Glen Braudrick

I was surprised to see that the powder was white - but I don't care what color it is as long as it works - it works! I've used FortiFlora (which I've had good luck with on other pets in the past) but it didn't work for this particular kitty. He has a sensitive stomach, as evidenced by the litter box and the aisle that leads to the litter box when he hasn't been around. Changing the food wasn't enough, but it helped for a few days. Unfortunately --- I bought additional boxes from other sellers (assembler) and they are old and completely different. They were brown so I knew right away something had changed, but the real fun started just after lunch when my cat became very ill with terrible diarrhea. Something has changed between the parties expiring now and 2020 compared to the parties expiring in 2021. The old sites are awful for my cat, but the new site has changed everything. Unfortunately I can no longer buy these online as I have no way of testing batches. I have contacted the manufacturer and am waiting for a response. I don't know what has changed between batches, but something has definitely changed. I have to think it's nothing active, but it was certainly enough to make a significant difference in my cat. If I could get a new batch I would give this five stars. When I look at an old lot, there are zero stars.
