Feline Urinary SO Aging 7+ Calm Loaf in Sauce Wet Cat Food
Verified Jun 20, 2026
This is a veterinary therapeutic wet food formulated for senior cats with urinary issues, combining urinary support with calming nutrients. Pork and chicken by-products and organ meats provide highly digestible animal protein, while added fish oil, taurine, and a tailored vitamin–mineral blend support overall senior health. The recipe is designed to help manage urinary crystals and stones while also supporting kidney function and helping stressed or anxious older cats stay comfortable.
This is a specialized, high-quality therapeutic diet for senior cats dealing with urinary tract issues, especially those prone to struvite or calcium oxalate crystals and stones. The formula uses nutrient-dense by-products and organ meats, has controlled mineral content, and includes targeted nutrients for kidney support, cognition, and calming—making it very appropriate for older cats under veterinary care. Because it is a prescription diet intended for specific medical situations, it should be used under the guidance of your veterinarian rather than as a general everyday food for healthy cats.

KibbleLab Review
Strengths
- Uses named animal by-products and organ meats (pork by-products, chicken, pork and chicken liver) that are naturally rich in high-quality protein, vitamins, and minerals for senior cats.
- Therapeutically designed to create a urinary environment that helps manage struvite and calcium oxalate crystals and support kidney health, which is a common concern in older cats.
- Includes fish oil and antioxidants to support overall vitality, brain health, and inflammation control in senior cats.
- Contains added L-tryptophan and hydrolyzed casein, ingredients that have been shown to have calming effects, which can be helpful for stressed or anxious cats whose urinary issues are triggered or worsened by stress.
Considerations
- This is a prescription veterinary diet formulated for specific urinary and kidney concerns and isn’t meant for healthy cats without these issues unless your veterinarian advises it.
- Contains common protein allergens for some cats, including chicken, pork, wheat flour, and wheat gluten, so it may not be suitable for cats with known food allergies or sensitivities to these ingredients.
- The as-fed protein and fat levels are on the modest side for wet cat food, which is appropriate for many senior and kidney-compromised cats but may not suit very thin or highly active seniors without veterinary input.

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
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.
03
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
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
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.
