Pigs
Pigs are highly social, curious, and intelligent animals who want to live just as much as we do. Pigs communicate with one another and have more than 20 recognised vocalisations. Pigs are also extremely clean animals; when given sufficient space pigs will take special care not to soil where they eat and sleep. Sows are incredibly maternal, building nests from their surrounding environment for their piglets and singing to them while nursing. Studies have shown that pigs have intelligence akin to that of a 4-year-old child.
90% of pigs bred for their flesh in Australia are raised in factory farms. Pigs in factory farms lead miserable lives in horrific conditions, which have been well documented in Australia.
