What we cats see, what dogs see and what humans see.

Dear George,
As you will know, all gardens in the immediate vicinity of any cat’s house legally all belong to the cat. I currently oversee around 6 gardens in my neighbourhood but unfortunately have to allow a rather uncouth dog to use one of my many estates. Being a lesser animal with barely any brains, he often barks at me, so I tend to taunt him from the fence, commenting on his wirey fur and lack of beautiful whiskers, while he tries in vain to jump up and reach me.
However, the other week while throwing some of my best insults at him and watching him jump and bark as usual, my beautiful red collar came loose and landed in the grass on his side. I have appealed to him to return it several times but he claims he cannot see a red collar in the grass. Is he just trying to wind me up or are dogs’ eyes as poorly developed as their brains?
Yours,
Chipstick

Dear Chipstick,
Dogs have inferior brains, yes, and they can't see the colour red. Humans are even odder. As well as an inferior brain, they have eyesight which shows them this unnecessary colour, red. We cats don't see red (except possibly a little tinge of it) because we don't need to. Whoever saw a red mouse? What we see, is what humans call colour blind. What I call feline eyesight is highly developed specialised vision.
We cats are far better than humans at seeing movement. Anything which moves we like - not just moving mice but also moving small furry toys from fishing rods! And also some people now believe that we may even see some ultraviolet!  And we can see in the dusk far far better than any human.
Instruct your human to look at  https://www.lasik-eyes.co.uk/see-world-pets-eyes/ which gives a good illustration of how animals see compared to humans. That way they will understand more about us. Oh yes, and incidentally they will be able to see how dogs see - if they are interested in this inferior species.
Yours
George. 
PS. On that website the gecko vision is very odd! But they taste good.
