Denyce, thanks for the info, that is interesting!

So they think that substance might not help her? The instruction added to the package I've got says it's exactly for that, struvite crystals and urolithiasis in cats and minks, it's creating an acid ph value in the bladder.

Anyway, I did some internet research myself and only found links to chemical pages which sounded very complicated (most of them in German and Danish), but I did not find a single info about this substance being harmful or dangerous.

I also saw the list with medicaments no longer produced, and it's been on it, but it doesn't look like there have been any risks, maybe it hasn't been profitable enough.

Luna, however, seems to be very happy with her "normal" food! She's more playful and active now (she was probably so hungry that she didn't have much energy left for playing during her diet) and she also seems to be over her constipation now.

So, let's hope these pills will have the desired effect on her bladder!
