? Food for Urinary Issues

So my cats have urinary issues (2 have cystitis and 1 had crystals a few years back). I've been feeding Wellness Chicken since the crystals episode as it's low in phosphorus. And of course, now they've changed the formula and upped the phosphorus.

So...what would you guys suggest? I've looked into Weruva but the calories are so much less I'd have to feed a lot more...and I am trying to be somewhat frugal. Any ideas for a good food for kitties that have had crystals (they were struvite) that won't break the bank?

 

Have you looked at anything on the low carb / low phos / possibly low protein list for CKD sugar kitties? https://docs.google.com/spreadsheets/d/112NvvzgxEBOtkb42rA0XR8GeShw9xXs9kccf9-olK7I/pubhtml
I don't remember how old that one is though...

Teasel is the only crystal kitty that I recall by memory

 

Thanks Yong! I'll check it out.
