English below the Swedish,
Friendly tänker: "Ser man på, det är här människorna förvarar all sin fina, goda och färggranna mat. Annat än den gråbruna sörja de serverar oss katter minsann. Nu när jag har hittatderas gömställe kanske jag ställer till fest och fixar oss katter någon färggrann läcker anrättning i natt".
English Version
Friendly is thinking: "Look at that! It is here the people store all their nice, tasty, and colorful food. That is something else than the grayish brown slop they serve us cats. Now when I have found their hiding place I might fix a party for us cats with some colorful tasty food tonight".

Jag funderade litet över hur katter uppfattar färger och efter litet googlande fann jag att färgsinnet inte var så värst utvecklat utan andra egenskaper var viktigare för kattens syn.
"A common myth is that cats are color-blind. Through tests and trials, scientists have determined that cats are able to differentiate between green, blue, and yellow, but not red. Feline cone cells are sensitive to blue and green but not to red. Color in itself is not very meaningful to cats. The world from the feline view is seen in a soft focus; a cat cannot hone in on details because of the large lens, which functions to gather as much light as possible. Motion-detecting rod cells in the retina make cats' eyes very attuned to motion, more than human eyes. Perhaps the most wonderful aspect of the cat's eye is the tapetum lucidum, a layer of reflective cells found behind the retina. Through the bouncing of light off the tapetum lucidum and back to the retina, rods and cones have a better ability to receive information."
Det sista är väl "kattöge-effekten".
