Though bassist Talena Atfield is pictured with the band on the album cover, Tanya Candler actually performed bass on Spit. The initial pressing on the album featured an alternate recording of the song "Paperdoll". This version is included on the Paperdoll EP.
Lead singer and guitarist Morgan Lander noted that the songs were "all written when we were 14 years old." She noted that Kittie was largely influenced by alternative music, listing "bands like Nirvana, Silverchair and Alice in Chains" as major influences. The band wrote the music first to serve as a "backdrop" to Morgan's vocals.
