Concentrations of amino acids (μmol/L) in plasma/serum from FD (n = 14), in-contact (n = 5) and control cats (n = 6).

<p>Concentrations of amino acids (μmol/L) in plasma/serum from FD (n = 14), in-contact (n = 5) and control cats (n = 6).</p

Metabolisable energy (ME; kcal/100g), protein and amino acid (g/1000 kcal ME) content of cat foods (n = 7) collected immediately after occurrences of FD.

<p>Also shown are [cystine + methionine] and [phenylalanine + tyrosine] concentrations. Recommended minimum nutrient requirements for growing and breeding cats (g/1000 kcal ME) are derived from the FEDIAF (2014) Nutritional Guidelines for Complete and Complementary Pet Food for Cats and Dogs [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174346#pone.0174346.ref017" target="_blank">17</a>].</p
