I gave this supplement to two of my cats and one of my dogs for 30 days for a fiber study. Then I have been giving it to all 5 of my dogs and 6 of my cats for the last three weeks. Previously, I had been giving them an inulin/acacia fiber blend. Since they were already used to taking fiber, I did a quicker introduction. They started with half the amount and increased to the full amount within a few days and had no problem adjusting. All the dogs and cats accepted the fiber mixed into their food without a problem. My cats tend to notice the slightest changes to their meal, so I was pleasantly surprised that they accepted the fiber so readily.
All of my cats usually have firm, healthy stools, so there wasn’t too much change. At times, some of their stools were narrower and seemed slightly dehydrated while taking the supplement, but that did not last and caused no concern.
Two of my dogs can randomly have softer stools from time to time. After taking the fiber, their stools are more consistently firm. The third dog tends to have smaller, less moist stools, and her’s did not change consistency at all. The fourth dog has firm, healthy stools, however after taking the supplement for a couple weeks, she had much smaller, dehydrated stools for a few days. The fifth dog, which was part of the study, had soft to loose stools on a more regular basis. The supplement made his stools more consistently firm.
Overall, the Complete Fiber Blend does make stools firmer. Going forward, I will adjust the amount given to the dogs/cats when their stools become too firm and/or dehydrated. This should be easy since the supplement is loose (not in a capsule) and easy to measure with the scoop provided. I am very satisfied with this product!
