In absolute darkness, i.e. a darkroom, no. Dogs and cats have better sight in the dark than we do in part because of a reflective layer in the retina behind the light-sensing cells, which reflects light back towards the source, and in effect gives the light-sensitive cells twice the chance to capture it. But if there’s no light at all, then the animals are as blind as we would be.
