Animal fat is a generic fat term used in pet food as an energy source and palatability enhancer. Under AAFCO definitions, it refers to rendered fat from any mammalian species. Because the exact source is not specified, it represents the lowest level of ingredient transparency. Named fat sources such as chicken fat or salmon oil are always preferable.
| AAFCO Definition | Animal Fat |
| Source | Unspecified (any mammal) |
| Function | Energy / Palatability |
| Energy | ~9 kcal/g |
| Transparency | Low (source unclear) |
| Controversy Level | Moderate |
The term animal fat carries source ambiguity. The exact animal origin is unknown and may vary by batch. That creates risk for pets with food allergies and makes quality control weaker than with named fat sources. Named ingredients such as chicken fat or salmon oil are preferable whenever possible.
Fat Source Transparency Ranking
| Designation | Transparency | VetKriter Note |
|---|---|---|
| Chicken Fat / Salmon Oil | High | Named and traceable |
| Poultry Fat | Moderate | Species group identified, but not specific |
| Animal Fat | Low | Source is unclear |
Frequently Asked Questions
Is “animal fat” harmful?
Not inherently. It provides energy and fatty acids. The main issue is source ambiguity. In pets with food allergies, an unidentified origin can create avoidable risk. Quality control and consistency are also harder to evaluate than with clearly named fats.
