We develop a family of predator-prey models with age structure and cannibalism in the prey population. It consists of systems of m ordinary differential equations. where m is a parameter associated with new proposed prey birth rates. We discuss how these new birth rates give the required flexibility to produce differential systems with well-behaved solutions. https://www.bekindtopets.com/mega-pick-Silbrade-Braid-Reinforced-Silicone-Tubing-1-4-ID-x-520-OD-x-1-hot-grab/
