Space Cats

  Depends on their response to wavelengths at rest, including IR (for blueshift) and UV (for redshift)

    Well we are assuming the space cat (i.e. it is not an ordinary cat) emitting a white light (it’s a glowing cat!), that is, the peak is in the middle of the visible spectrum. The cat becomes closer to red as it moves away and to blue when it is moving towards us. If it goes fast enough, the peak shifts to IR (past the red) or UV (past blue/violet)

    But yes, if it was a normal non-space cat, the peak would be in the IR normally (since cats are quite cool, in both senses of the word), and as it moves away the peak shifts to longer wavelengths, and as it moves towards us, it will go to shorter wavelengths, possibly becoming visible if fast enough.

      This is true about cats’ radiation but we usually mean reflectivity when describing a cat’s color. This of course means there is a light source illuminating the cat and the wavelengths observed also depend on the properties of the light source.

      Wait, is the spacecat also a raycat? And also radioactive? This is going into the book of cryptids so make your answer weird

  With respect, some space cats accelerate butthole first
