Good but too expensive
My cat has chronic cystitis because of anxiety and these really help, but you’d have to give them... pretty much forever. I stopped and only gave her one a week, and she got cystitis again. The price is VERY expensive. If this company really wanted to help poor suffering kitties—since cystitis is so painful—they’d lower the price (or Zooplus would). But yes, they do work, just way overpriced.
