A fishing cat, National Zoo, Washington DC.
”The solitary living fishing cats are thought to be primarily nocturnal. They are very much at home in the water and can swim long distances, even under water. Females have been reported to range over areas of 4 to 6 km2 (1.5 to 2.3 sq mi), while males range over 16 to 22 km2 (6.2 to 8.5 sq mi). Adults have been observed to make a “chuckling” sound and likely have other calls similar to those of domestic cats.”
