About Pet8
Pet food packaging is designed to sell. The front of the bag talks about wilderness, instinct and premium recipes; the part that actually tells you what's inside is the small print on the back.
Pet8 reads that small print for you. You photograph the ingredients panel, we pull out the facts — the ingredient list and the analytical constituents — and a fixed set of rules turns those facts into a score from 0 to 100 and a grade from A to E.
Why the rules are fixed
Reading the label and judging the label are deliberately kept apart. Extraction just gathers facts; the scoring is plain, published logic. That's what makes the same product score the same way every time — and lets us show you exactly which ingredient moved the number.
What we look at
Named protein quality
We look for real, named meat or fish near the top of the list — “chicken”, not “meat and animal derivatives”.
Protein on a dry-matter basis
Water is removed from the maths so a wet food and a dry food can be compared fairly against published feline nutrition baselines.
Fillers
Cheap grain and plant bulk high in the ingredient list counts against a food, especially in the first few ingredients.
Additives
Preservatives and colourings are grouped into poor, debated and good. Where the science genuinely disagrees, we say so.
Transparency
Labels that name specific ingredients and disclose percentages score better than vague blanket terms.
A note on what this isn't
Pet8 is an informational tool, not veterinary advice. A grade is a guide to label quality — it can't know your cat's age, health or allergies. Talk to your vet before changing a diet.
