Cosma is a premium cat food brand exclusive to ZooPlus, and over the past decade it has quietly become one of the most talked-about cat food brands in the UK among knowledgeable pet owners. You will not find it in Pets at Home, Tesco, or any high street retailer โ it exists exclusively through ZooPlus UK, which has allowed the brand to maintain both quality and price discipline without the compromises demanded by mass-market retail channels.
The brand spans two distinct lines: Cosma Nature (the ultra-simple premium range) and Cosma Asia / Thai / Soup (the higher-volume everyday range). Together they cover almost every cat’s preference, budget, and dietary requirement across over 300 SKUs โ the largest single-brand cat food offering available through ZooPlus.
We’ve reviewed the full Cosma range available in the UK for 2026, testing palatability across multiple cats of varying sensitivities, preferences, and life stages.
Cosma Nature vs Cosma Asia vs Cosma Thai: What’s the Difference?
Cosma’s product lines are meaningfully distinct โ not just cosmetic rebranding:
- Cosma Nature: The premium line. A single named protein (tuna, chicken, or ocean whitefish) in a natural broth. Grain-free, additive-free. Ingredient list: protein + broth + minerals. That is all. This is for cats with allergies, older cats on kidney-support diets, or owners who demand maximum ingredient purity.
- Cosma Asia: Premium tins in a natural jelly. Larger variety of proteins available (duck, salmon, tuna, king prawn). Slightly more complex ingredient list than Cosma Nature but still grain-free with named proteins and no artificial colours or preservatives.
- Cosma Thai: Soupy pouches with a high liquid volume. The broth in these pouches functions almost as a drinking supplement โ especially effective for cats who refuse the water bowl. Very high in moisture content.
- Cosma Snackies: Freeze-dried treats made from 100% single protein. Coated or plain varieties. Excellent as a high-value training reward or pill-hiding vehicle.

Our Detailed Reviews
1. Cosma Nature Adult Tuna in Broth โ Best Overall
Open a Cosma Nature tin and the visual encounter is instantly different from almost every other wet cat food: translucent broth, clearly visible chunks of actual tuna, and a light gelatinous texture as the broth cools. The ingredient list printed on the underside of the lid lists four items: skipjack tuna, tuna broth, tapioca starch, and mineral salts. The simplicity is deliberate and the results are measurable.
Why we chose it: Independent digestibility testing consistently shows that single-protein, low-additive foods like Cosma Nature are absorbed more efficiently than complex blended foods. For older cats (7+) whose kidneys have reduced phosphorus processing capacity, the low phosphorus concentration in Cosma Nature (compared to protein-blended foods) is genuinely beneficial.
2. Cosma Nature Saver Pack 12 x 70g โ Best Value
Cosma Nature tins in individual 70g units are the perfect single-serving size for one cat. The 12-pack economy box brings the per-tin cost down significantly while maintaining the identical product quality. At ZooPlus, rotating through sale events and loyalty points, Cosma Nature becomes genuinely competitive with cheaper brands on a cost-per-100-kcal basis when factoring in its superior digestibility (less wasted food = fewer portions required).
3. Cosma Asia Adult in Jelly โ Best for Rotating Proteins
The Cosma Asia line is where Cosma flexes its variety. Available in chicken, tuna, salmon, duck, king prawn, and various combination flavours โ all in a firm jelly rather than a broth. The jelly format suits cats who prefer a denser texture than the more liquid Cosma Nature broth. The proteins are named, the grains are absent, and the variety is extraordinary.
Why we chose it: Rotating through multiple proteins in the Cosma Asia range prevents food boredom (a real issue with cats who eat the same flavour daily for months) and reduces the risk of developing a single-food sensitivity by ensuring diverse protein exposure.
4. Cosma Soup (Thai) Broth Pouches โ Best for Hydration
These tiny 40ml pouches are not conventional wet food โ they are cat-safe broths, designed to be poured directly over food or given as a drink from a small saucer. The liquid to solid ratio is far higher than any standard pouch, making them the single most effective commercial tool for increasing a cat’s daily water consumption. For cats with early kidney disease, urinary crystals, or any condition where the vet has told you “he needs to drink more,” this is the product to reach for.
Why ZooPlus is the Only Place to Buy Cosma
Cosma is a ZooPlus exclusive, developed as a premium house brand to provide ZooPlus customers with a product of boutique-brand quality at a sustainable price point. The lack of retail distribution means no brokerage margin is added โ what you pay goes directly to ingredients and packaging.
This also means you cannot buy Cosma from any UK marketplace, high street retailer, or comparison website. All Cosma links on this page are direct AWIN affiliate links to ZooPlus UK.
