Rusty-spotted cats are mostly nocturnal, but zoo observations show that they’re not strictly nocturnal or crepuscular; sexually active individuals are actually more active in the daytime.
When rusty-spotted cats were first brought to the Frankfurt Zoo, they were presumed to be nocturnal because most sightings had been at night or at early dawn and late evening. They were then placed in a nocturnal environment in the zoo, but after monitoring the behavior of the cats, it was shown that the species may not be strictly nocturnal or crepuscular. Sexually active animals were more active during daylight hours.
