Just what the title says. We've been pruning back our crape (crepe) myrtle trees and have many good width straight pieces. Does anyone know if these would be safe for the rats to use as branches to climb on or as chew toys? I would let them dry out for a long time first of course... I'm curious about this as they are listed as safe on a bird perch wood list I found, but I haven't found anything about rats or rodents using them to chew on.
