I agree with what you say that TOO much of a good thing like probiotics is not a good thing. I add some feline Forti Flora to our ferrets' soup about twice a week, but not a lot. I find that this does help keep things well balanced in terms of proper digestion, while still letting their bodies do most of the production of the 'good' bacteria. Luna and Trinny have some stomach problems, so they get a little more of the Forti Flora when things act up, but I still try to be very careful not to over do it with the supplementation. I believe that it has helped a lot in managing IBD, and it's also a very good thing when one of them has been on an antibiotic.
