Distribution of the cats according to their response to L-theanine. The reduction in the global score reflecting stress-related parameters was calculated at D30 relative to D0 (%) for each cat. The number of cats showing no reduction (no response to L-theanine), a 1–29% reduction (poor response), a 30–49% reduction (fair response), a 50–79% reduction (good response) or a reduction of 80% or more (excellent response to L-theanine) in their global score, are reported (total n = 33)
