Cat5 is a electropop duo from Göteborg. Behind the name are Christina Roos and Hanna Göranson. They started to write and produce music together in 2005 and quickly got a big hit with 'Sexy'. Things started to snowball for them and during the fall they managed to get signed to the hottest indie label in Sweden, 'Service', release the single 'Play this loud / Sexy' and make a popular remix of The Embassy's hit 'Some Indulgence'. On their self-titled debut album they mix smashing dance hits with electronical ballads.

The name Cat5 originates from Hanna's old cat that could do a high five.
