Chandab what is it you added?
I know there are many probiotic products out there... I had some Probios dispersible powder and tried it, he wouldn't eat any of his food that I put the Probios into (not one bite, don't blame him, it stinks). So, I started searching for something different. I'd found several different products, including FastTrack which got great reviews, but came in a fairly large bag; with as picky as he has gotten I didn't want to be stuck with a big bag that no one would eat, so I kept searching. I was looking on the Smart-Pak website and came across their brand; SmartDigest and I could get it in a small container (4 week supply), so I ordered the small container.
I was skeptical when it came, it was a granular/powder product, he usually just blows them out of his dish, but we tried it; first I just put the scoop in his bucket, he sniffed it but didn't snort and blow it out of the bucket (but he wouldn't eat it, as its powder), so I added his scoop of oats to the bucket and mixed it and he tried it and didn't make his icky face nor spit it out, so I mixed in the rest of his meal and he's been eating it ever since (we will finish up the first tub tonight, and I have a new one ready for tomorrow).
Smart-Pak actually has a few different probiotic products, but I started with the SmartDigest since it was the most economical should he decide he doesn't like it. This should be the link to SmartDigest:
