  We propose that chiral anomaly of Weyl superconductors gives rise to negative
thermal magnetoresistivity induced by emergent magnetic fields, which are
generated by vortex textures of order parameters or lattice strain. We
establish this scenario by combining the argument based on Berry curvatures,
and the quasi-classical theory of the Eilenberger equation with quantum
corrections arising from inhomogeneous structures. It is found that the chiral
anomaly contribution of the thermal conductivity exhibits characteristic
temperature dependence, which can be a smoking-gun signature of this effect.
