Hello, Can anyone please tell me what are the very lowest carb dry foods? And I believe I read about a zero carb dry food as well if that is possible (Young Again?) I remember there were 1 or 2 brands that would send a free sample. My need for no/low carb dry is for a kitty with mammery cancer believe also spread to lungs. She will not eat wet and carbs feed cancer. Info appreciated as Dr Piersons chart no longer lists dry Thx so much !
