Feline Urinary SO + Satiety + Calm Loaf In Sauce Wet Cat Food
Verified Jun 15, 2026
This is a veterinary therapeutic wet diet for adult cats that targets urinary health, weight management, and stress-related issues. It uses chicken and pork by-products and liver as the main protein sources, with added fiber to help with satiety and a specialized mineral balance to support a urinary environment that is less favorable to crystal and stone formation. The formula also includes fish oil, L-carnitine, and specific nutrients from hydrolyzed casein that are intended to support calm behavior and overall wellbeing.
Nutritionally, this is a well-designed prescription wet food for adult cats that need support for urinary tract health alongside weight control and stress management. The moisture-rich loaf texture can help increase water intake, and the controlled mineral profile and S/O index are specifically aimed at reducing the risk of certain urinary crystals and stones. It’s most appropriate for cats under veterinary supervision who have a history of urinary issues and/or need help with weight loss or weight maintenance.

KibbleLab Review
Strengths
- Formulated as a complete and balanced veterinary therapeutic diet specifically targeting urinary health, weight management, and calm behavior in adult cats.
- High moisture content and an S/O urinary index to support a urine environment that is less favorable to struvite and calcium oxalate crystal formation.
- Uses nutrient-dense organ meats and by-products (chicken and pork liver, pork by-products) as primary protein sources, plus added taurine, methionine, and L-carnitine for metabolic and cardiac support.
- Includes added omega-3–rich fish oil and joint-support nutrients (glucosamine and chondroitin), which may provide additional benefits for overall health in older or overweight cats.
Considerations
- Protein and fat levels are on the lower side for a feline diet on an as-fed basis, which is appropriate for many overweight cats but may not suit very active or underweight cats without close veterinary guidance.
- Contains chicken and pork, which can be problematic for cats with known food allergies or sensitivities to these proteins.
- This is a prescription therapeutic diet intended for specific urinary and weight-related conditions, so it should be used under veterinary direction rather than as a general everyday food for healthy cats.

Top 5 Ingredients Explained
01
Water
Water is an essential nutrient and the primary solvent and moisture component in pet foods, especially wet and canned diets, and is also used in processing and to adjust texture and palatability. It is vital for digestion, nutrient transport, temperature regulation and waste removal in dogs and cats; pets must have constant access to clean water as dehydration can quickly lead to serious health issues and requirements increase with activity, heat, or illness, while moisture in wet food can help meet part of their daily needs.
02
Chicken Liver
Chicken liver is a nutrient-dense organ meat commonly used in pet foods and treats as a highly palatable protein source and flavor enhancer, providing concentrated vitamins (especially vitamin A and B-complex), iron, and copper that support energy metabolism, red blood cell formation, and skin/coat health in both dogs and cats. Because it is so rich, liver should be fed in moderation—excessive intake can cause vitamin A toxicity, and its high fat content and risk of bacterial contamination mean it should be properly sourced or cooked and limited for pets with pancreatitis or specific dietary restrictions.
03
Pork By-Product
Pork by-product is a common protein and flavoring ingredient in pet foods made from non-rendered portions of the pig such as organs, connective tissue and trimmings, supplying animal protein, fat, B vitamins, iron and other trace minerals that help support energy, muscle maintenance and overall nutrition for dogs and cats. Because composition and fat content can vary by source, owners should be aware of potential pork sensitivities, higher caloric density, and sourcing/quality differences; ensure the complete diet meets species-specific requirements (for example, cats need adequate taurine) and consult the manufacturer or your veterinarian if you have concerns.
04
Pork Liver
Pork liver is an organ meat used in pet foods as a nutrient‑dense source of high‑quality protein and concentrated vitamins and minerals—notably vitamin A, B vitamins (including B12 and folate), iron and copper—that support red blood cell production, skin/coat condition and overall metabolism. Because liver is very rich in vitamin A and certain minerals, it should be included in limited amounts to avoid hypervitaminosis A or mineral imbalances and must be properly processed to reduce pathogen risk; pets with urinary stone issues or a pork sensitivity should use caution.
05
Brewer's Rice Flour
Brewer's rice flour is a finely milled byproduct of rice processing used in pet foods primarily as a digestible carbohydrate, binder and texture enhancer rather than a significant protein source. It supplies readily available energy and is often well tolerated by dogs and cats (less commonly allergenic than wheat), but it contains little protein or essential nutrients so formulas must be balanced around it; additionally, high-rice diets can be relatively high‑glycemic and rice can accumulate trace arsenic, so it’s best used in moderation within a complete diet.
