Alphas are piggies, as taken from the PETA article, On 11 Reasons to Love Pigs, "Pigs are playful, friendly, sensitive, and intelligent animals. They've long been considered smarter than dogs, and the complexity of their social lives rivals those of primates. Much like people, pigs are soothed by music, love playing ball, and even enjoy getting massages." Ne, Fe, Si, Ti.
Betas are hyenas cuz cmon have you never seen The Lion King? The constant gossip, the aristocracy, the power games.
Deltas are cats since they only come to you when it pleases them (mostly from Te based needs, the Fi comes later with time).
And Gammas are man's best friend, loyal, loving, can be aggressive.
