Well, not the most unpleasant topic. Anyway, one of our cats-- and recently the two oldest ones-- have had this problem where they're blocked, and have trouble urinating... we've been shooting chicken broth with vitamin C as well as "No Fus" tablets crushed up in water into Jasmine, at least, and hiding chunks of tablets in hamburger for Streak. The thing is, it keeps re-occuring if we stop at all. Any ideas?
