How We Review Pet Products

We start by mapping the UK market for each category — identifying every product available from reputable UK retailers. We include products that are sold in the UK and widely bought, whether or not we earn from them; where a product has no affiliate programme we still list it and say so.

• ▸We check Pets at Home, Zooplus, Amazon UK, VioVet, and specialist retailers.
• ▸We exclude products available only through US or EU sites with no UK shipping.
• ▸We identify products with verifiable ingredient or formulation transparency.

We compare shortlisted products against their published ingredients, specifications, and pricing, cross-checking manufacturer data against independent sources. Where we've genuinely bought and tried a product ourselves, we say so directly in the review — we don't claim hands-on testing we haven't done.

• ▸For food and supplements: we compare ingredient panels, sourcing claims, and price per serving against manufacturer data.
• ▸For physical products (beds, toys, leads): we compare specifications, materials, and stated durability claims.
• ▸For insurance: we compare policy documents, excess structures, exclusions, and claims processes.

Every health or nutrition claim in our guides is checked against published sources — including the PDSA and NHS guidance where it's relevant to pets — before publication. We flag any claim we can't verify and don't publish health advice we can't source.

• ▸Fact-checking is mandatory for any guide making a health, nutrition, or safety claim.
• ▸Claims we can't verify against a published source are removed or clearly flagged as our opinion, not fact.
• ▸We link to our sources so you can check them yourself.

We score each product across five criteria using a weighted methodology. Products must achieve a minimum threshold to be included in a 'Best of' guide. A high score is required to earn our 'Pawwala Pick' badge.

• ▸Quality / ingredients (30%): formulation, sourcing, certifications.
• ▸Value for money (25%): price per serving/unit versus quality.
• ▸Real-world effectiveness (25%): how the product is likely to perform, judged from published specifications, independent sources and the pattern of public owner reviews. We say when this is desk research rather than our own use.
• ▸UK availability & ease of purchase (10%): stocked by reputable UK retailers.
• ▸Transparency (10%): brand's honesty about ingredients, manufacturing, and clinical evidence.

Our reviews are not set-and-forget. We revisit guides on a scheduled basis and update them whenever: a formula changes, a product is discontinued, a price shifts significantly, or community feedback reveals issues we missed.

• ▸All guides display a 'Last reviewed' date at the top.
• ▸We monitor community feedback, vet literature, and brand announcements.
• ▸If a product we previously recommended receives consistent negative feedback, we re-check our research and update our rating.

Pawwala is researched and written by one editor, who also manages the affiliate relationships, so commission rates are known when pages are written. That is why we publish our scoring criteria: rankings follow the criteria, brands cannot pay for inclusion or a better rating, and products without an affiliate programme are ranked on the same basis.

• ▸Paid content, if we ever publish it, will be labelled 'Advertisement feature' and kept out of our rankings.
• ▸We decline review requests where brands require editorial approval over our conclusions.
• ▸Products from brands we have a direct commercial relationship with are identified in the review.
