From Fluffy-Pie's point of view
…Sarah Wilson and Brian Kilcommons wrote an interesting story in the October 15th Parade on how animals see.
…HA always heard dogs see only black & white. In daylight, scientists think, they actually see fuzzy blues and yellows. In dim light, a huge array of grays (many more shades of gray than we can see, which may account for the desire to play all the time).
…Dogs also can’t see well close up.
…Cats can see in dark six times darker than we can. Cats probably see pastels, and miss some colors altogether.
…Birds are the color freaks! The world is a color fest for them. For every color we see, birds can see many shades. Birds can also see UV light, which helps them locate their babies in a shady nook.
…If you laid out human smell receptors, they would cover a stamp. A dog’s would cover a large hankie.
…That’s why dogs get the smelling jobs—drugs, gas leaks, criminals, cancer.
…Yes, some can detect cancer. You may get a dog scan instead of a CAT scan someday.
…That sounds like a good day to HA. At least, dog-wise.
