- Cats have a higher protein requirement than even most other carnivores.
- Cats cannot downregulate protein metabolism. If they do not get enough meat-based protein, they rob their own muscles for it.
- Cats must have preformed arginine and taurine (amino acids which humans synthesize). A lack of these in the diet rapidly causes blindness and death: only animal protein provides these at levels cats require.
