are cats crepuscular animals
Species most active during both dawn and dusk (or twilight), are crepuscular. You could call crepuscular species both matutinal and vespertine. Some examples of crepuscular animals are skunks, fireflies, and deer. Pets generally considered crepuscular are dogs, cats, rabbits, and hamsters. As @Critters notes in the comments, sometimes hamsters are considered nocturnal.
