Abstract: The first neutron star was observed in 1968. Since then more than a thousand of neutron stars were discovered, but despite the single equation of state leading their existence, many different classes of neutron stars are known in our Galaxy, with highly different and puzzling observational properties. I first review all the different flavors of neutron stars we know thus far, and the variety of different physical mechanisms involved in their multiwavelength emission. I will then focus on the RRATS (Rotating RAdio Transients), a newly discovered class of sources, maybe another puzzling flavor in which the neutron stars are confusing us.
