A study published in 2006 indicates that feeding cats a probiotic supplement can result in systemic and immune system health benefits as well as positively altering GI flora.
The study ran five weeks and involved 15 healthy adult cats. Results showed the L. acidophilus strain given to the cats survived transit through the GI tract and decreased the numbers of two types of unfriendly gut bacteria.
In addition to improving the good-to-bad GI bacteria balance, administration of the probiotic also improved:
- performance of phagocytes – cells that absorb waste and harmful microorganisms in the bloodstream and tissues
- production of cells involved in immune system performance.
