I was just thinking about this. Rocket absolutely loves the Nutro Grain Free Perfect Portions, but they're not on the list - I usually only feed him the pate varieties; there are a couple listed as "cuts in gravy" too. I'm attaching a photo. I've been wondering if anyone here feeds these to their cats too. I contacted the manufacturer about them several weeks ago, and they got back a few days later - she said all the pate varieties are under 1% carbs (as-fed, not dry matter). I didn't know to ask about phosphorus at the time, but I do now (Rocket has acromegaly, so we're trying to do what we can to keep his kidneys healthy). Chewy lists the chicken variety, for example, as .34% phos (as-fed) and 1.55 (dry matter), for what it's worth. I find if I look for foods on Chewy often someone has asked questions about carbs and phos already, if that helps.
I know Tiki Cat has several varieties that are very low/no carb, and low phosphorus. But Rocket doesn't really like them. =/
