Concrete Patio replacement-stop animals underneath

I am replacing a 35 x 15 ' patio. The 35 is against the house. This time, rebar will be drilled into the foundation to stop sinking away. One contractor suggested a footing (2' deep so not below the frost line) all around to stop animals. He would tie rebar from footing to pad. The other suggested he pour the edges 12" deep and the top 4", no vertical rebar in the 12" deep sides. He said the center would heave if all 4 sides are tied to the edges. We are in Zone 4/5 depending on map. Any suggestions?
