| Main ingredient | Clearly identified liver, such as chicken, beef, or rabbit liver | A named animal ingredient makes the product easier to evaluate and supports ingredient transparency. | Vague terms such as “meat derivatives,” “animal protein,” or “meat flavor” without further detail |
| Ingredient simplicity | A short recipe with liver and only necessary processing ingredients | Fewer ingredients can make it easier to identify potential allergens or digestive triggers. | Long ingredient lists containing several unnamed animal ingredients, artificial colors, or unnecessary flavorings |
| Vitamin A level | A product intended for occasional feeding, with serving directions and calorie information | Liver is naturally very high in preformed vitamin A. Excessive long-term intake can contribute to vitamin A toxicity and skeletal problems in cats. | Large daily portions, frequent feeding, or combining liver treats with other high-vitamin-A supplements |
| Nutritional purpose | A statement that the product is a treat or complementary food, not a complete diet | Treats generally do not provide all nutrients required for a cat’s daily diet. | Using liver treats as a meal replacement or allowing them to displace nutritionally complete cat food |
| Calorie information | Calories listed per treat, gram, or recommended serving | Calorie information helps owners keep treats within the commonly recommended limit of about 10% of daily calories. | High-calorie treats given freely or without reducing the regular food portion when appropriate |
| Toxic ingredients | No onion, garlic, chives, leeks, or products containing these ingredients | Allium plants can damage red blood cells and may cause anemia in cats. | Fresh, powdered, dehydrated, or concentrated forms of allium ingredients |
| Sweeteners and additives | No added sweeteners; no xylitol or other unnecessary sugar substitutes | Cats do not need sweetened treats, and xylitol should not be included in pet products. | Sugar, syrup, xylitol, excessive salt, artificial colors, or strong unidentified flavor enhancers |
| Raw versus cooked | Cooked, freeze-dried, or dehydrated product made under controlled food-safety conditions | Raw animal products may carry pathogens such as Salmonella or Listeria, which can affect pets and people. | Unprocessed raw liver, unclear handling instructions, or feeding practices that increase household contamination risk |
| Moisture and storage | A clear use-by date, lot code, sealed packaging, and storage instructions | Proper storage helps limit spoilage and contamination after opening. | Damaged packaging, mold, unusual odor, moisture in a dry product, or treats stored beyond the stated period |
| Texture and size | Small, appropriately sized pieces that can be broken into controlled portions | Smaller portions support calorie control and may reduce choking risk when supervised. | Large, hard pieces offered to cats that gulp food or have dental or swallowing difficulties |
| Allergen and tolerance check | A single, clearly named animal protein when a cat has a sensitive stomach or suspected food allergy | A simple protein source makes it easier to monitor reactions such as vomiting, diarrhea, or itching. | Introducing several new treats at once or continuing a treat that causes repeated digestive or skin symptoms |
| Special health conditions | Veterinary guidance for cats with liver disease, kidney disease, obesity, urinary issues, or prescription diets | Medical diets and individual nutrient limits can make ordinary treats unsuitable. | Adding liver treats without checking with a veterinarian when the cat has a diagnosed condition |
