Food suggestions for cat with uti

[Bon]

Hi!

My cat, Bailey, has an infection which could lead to her having crystals.

Her vet suggested I buy Royal Canin Feline Urinary SO cat food (kibble or canned).

I don't want to buy that just because the vet's office sells it. I know Royal Canin is a good food, though.

I feed our pets Holistic Brands, so I was wondering if anyone else has a similar situation and could recommend some Holistic Brand cat foods that I could try that might be just as good or better than the vet's recommendation.

Also, Bailey is about 6 lbs overweight, so if there is a food that can help with both, even better!

Thanks!

Bonnie
