As such, livestock includes animals such as cattle, horses, sheep, and fur-bearing animals, but does not include farmed birds (turkeys, chickens, pigeons, geese), fish, shellfish, amphibians (frogs), and reptiles. It also does not include animals kept as pets.

The most common way to separate pets from farm animals is, simply, by asking if people eat them. We eat beef, so cattle are livestock, whereas we don’t eat dogs so they are pets. Sep 27, 2016

Ants have colonised almost every landmass on Earth. Their population is estimated as between 1016–1017 (10-100 quadrillion). With an estimated 20 quadrillion ants their biomass comes to 12 megatons of dry carbon, which is more than all wild birds and mammals combined.
