Thanks for the advice. I definitely need to try to get some cranberry juice. Cranberry, in addition with Vitamine C, is only available in capsules here, and I'm not sure if Luna will eat those. But it's worth a try though.

As Luna tends to have struvite crystals, we try to acidify her urine with UroPet paste. That's a paste I'm mixing under her food every day. She's also on Cantharis, a homeopathic pill that seems to help her a lot. But still, her UTIs occur from time to time; twice a year, as it seems...
