Editorial standards

• Accuracy first: every specification comes from the maker's or seller's published information.
• No veterinary or diagnostic claims for health-tracking features; we report what a device measures.
• Microchip compatibility only as the maker documents it for that exact model.
• Consumable compatibility only as the maker or the consumable's seller documents it.
• Discontinued products are removed or clearly labelled, never recommended.
• Commissions never decide which products we cover or how we rank them.
