Hello experts - I'm looking for recommendations for a good food for a cat with UT issues - we're having issues with crystal build-up, and the vet has recommended a changed diet to manage in the long term. The only food they recommend is Royal Canin, though, and while in the past she has been fine on this, we had it last week and it gave her terrible diarrhoea. I'm sure I've heard that mentioned as a downside of RC before, but am not sure what I should be looking for in an alternative.
NB - she does also need to lose some weight, and I plan also to get her a water fountain to increase her fluid intake.
