Biddy and Sunflowers

Apparently cats can only see the colours yellow and blue clearly!
Red and green appear greyish! This is according to John Bradshaw's latest book called Cat Sense: The Feline Enigma Revealed.

To test out this theory I bought some sunflowers today and put them in the bedroom for Biddy to enjoy. She was quite surprised to see them - she looked at them for some time so hopefully she enjoyed their bright yellow colour.
