This is a complete wet food formulated specifically for sterilised cats (i.e., cats that have been neutered/spayed) — as noted on registration lists for the brand in the “Sterilised Cat Chunk Lamb in Gravy 400 G” variant. 
Format: 400 g can (or similar large-can size) of chunks in gravy, lamb-flavour.
Texture: Chunks of meat in a gravy (wet, moist) which tends to appeal to cats who prefer softer/juicy meals over dry kibble.
🥩 Key Features & Benefits
Here are what you can expect and why they matter:
Lamb as the flavour/primary animal protein: Provides a different protein source (lamb) which can be good for cats with sensitivities or simply for variety.
Formulated for sterilised cats: After sterilisation, cats tend to have a somewhat lower energy requirement and may be more prone to weight gain or changes in urinary/renal health. A formula marked “sterilised” is generally tailored (via fat, calorie content, mineral levels) accordingly.
Chunks in gravy: This texture helps increase moisture intake, which is important for urinary tract health in cats (especially sterilised ones).
Complete food: It means it is intended to meet all nutritional needs of the cat when fed as directed — so you don’t need to add supplements.
Convenient size: 400 g means fewer cans to store, usually economical for multi-cat households or for feeding over multiple servings.

Because the formula is for sterilised cats, fat and calorie content often are moderated to prevent weight gain.
Moisture content is high (as expected in wet food) which helps with hydration and urinary health.
