I came across some interesting info I'd like to share.
“The microflora in a cat's small and large intestine are different than for people, so
we can't assume that human probiotics will work in cats,”
The strains that cats tend to do best with are those of the
Bifidobacterium and
Enterococcus families.
Bifidobacterium tends to live in the small intestine, whereas
Enterococcus generally resides in the colon (large intestine). So each strain could have a different function when it comes to promoting health.
Bifidobacterium is more involved with digestion and the
Enterococcus aids with the formation of normal feces and helping to maintain colonic health. Mahaney says you really can’t go wrong with purchasing a product with additional bacteria strains but stresses that it’s important to opt for a supplement that contains the two bacteria mentioned above.
Antibiotics are notorious for wiping out healthy gut flora. In order to combat this, Frey recommends giving a cat a daily dose of probiotics when a cat has been on antibiotics in order to help repopulate the digestive tract. To be proactive, pet parents can also give their cats probiotics at the same time that they start a dose of antibiotics. “The probiotics are often extended for several weeks beyond stopping the antibiotic, as it takes a long time to make those good bacteria stick,” says Frey.
Risks and Considerations of Probiotics for Cats
Adverse effects of probiotics are rare in cats. Frey, however, warns that cat owners should choose their probiotic brands wisely. “The supplement industry is loosely regulated and there isn't a governing agency that requires a company to prove its label claims for amounts and strains. Companies only have to respond to complaints,” she explains. Human supplement manufacturers are required to have more oversight than veterinary ones. There is, however a veterinary organization called
National Animal Supplement Council (NASC) that does provide some oversight. Frey recommends giving cats a veterinary product that
has the NASC label or a product from a company that also produces human supplements and foods whenever possible.
But at the end of the day, it all comes down to what works the best for your specific pet. “We know so little about probiotic and normal flora populations in animals. There is much to learn,” says Frey. “No one product works for every animal so trying different probiotics and watching for results is a good common sense approach.”
