Abstract: 
 Using a fixed point theorem of strict-set-contraction, we
 some established the existence of positive periodic
 solutions for the neutral logistic difference equation,
 with multiple delays,
 $$
 \Delta x(n)=x(n)\Big[ a(n) -\sum_{i=1}^{p}a_{i}(n)
 x(n-\tau_{i}(n))  -\sum_{j=1}^{q}c_{j}(n)
 \Delta x(n-\sigma_{j}(n))\Big].
 $$
