I’ve noticed that lately whenever I feed Tesla whole leaf greens (endive etc.), she almost immediately runs right for the white crunchy part at the base. Today I put what was left of an endive head in with her without breaking off the leaves; she ate the darkest green bits then immediately began crunching on the base, ignoring the bits in between. (She eventually ate the whole thing, though!) So it’s got me curious, do your torts have a favorite part of their plants to eat?
