In an NME article the song was described as being "flamenco-flecked." When earlier describing the album on Twitter, Matt was possibly referring to 'Animals' as 'face melting metal flamenco cowboy psychedelia.'
'Animals' is about economies collapsing under the weight of stock market savagery, of industries desperate to "advertise, franchise… kill the competition," and of the greed of bankers who Matt claims should "kill [themselves]." Matt says: "This song is conjuring up the rawest form of that feeling of 'look what humans are capable of doing, it's shocking.'"
According to Jeuxactu, a French magazine, the song has a fast beat, and while heavy riffs seem expected, the song has a simple, short guitar solo. 
'Animals' is the first Muse's song written in 5/4 time signature. 'Animals' also features Muse's first use of polyrhythms, where in the final section of the song, the Drums have a 4/4 time signature, while the remainder of the instruments continue with a 5/4 time signature
Matt said in an interview with 1Radio that this song was influenced by a Queens of the Stone Age song that has a 5/4 time signature. He also Animals is the hardest song to play live off The 2nd Law due to having to play lead guitar and sing at the same time.
The name of this working title song was shown on a photo posted by the Muse account on Twitter.
Animal, animal Don't take anything else Out of control, you're out of control Strike those in distress
Analyse, Advertise spread out Bend more rules Buy yourself an island
Animals, animals Buy when blood is on the street Out of control, you're out of control Crush those who beg at your feet
Analyse, franchise, expand Kill the competition And buy yourself an ocean
Advertise, downsize When your... (?) Kill yourself Come on and do us a favour
