Medium Risk Quality issue

Plant-based fat sources only

Score impact: −10 pts per affected product


Exclusively plant-derived oils as the fat source. Cats cannot efficiently convert ALA to EPA/DHA — animal fat or fish oil is necessary.

Score Rationale

Cats lack sufficient delta-6 desaturase activity to convert short-chain ALA (from plant oils) into long-chain EPA and DHA, which are required for neurological function and vision. A diet relying exclusively on plant-derived fats risks long-term essential fatty acid deficiency — particularly DHA, which is critical for retinal and brain development.
