I don't think it is available in the U.S., only in several European countries and Canada. I wish we could get it here. I know JCAT uses it in Germany for her IBD kitty and I think she still has been able to avoid steroids.
Many thanks for your reply....I will see if there is a source in Canada. Butyric acid is a potent treatment for some people with IBD, and it is very safe. I would love to get some of this for my kitty.
