How Bastet became a god?

Mostly by Festivals; Bast's festivals included the 'Procession of Bast', 'Bast appears to Ra', the 'Festival of Bast', 'Bast Goes Forth from Bubastis' and 'Bast guards the Two Lands'. There was even a 'Festival of Hathor and Bast', showing the connection between the two goddesses.
