I love cats. They just have such cute faces. But sometimes I wonder about their intelligence. I own a eighteen pound old tomcat and at times he seems to demonstrate Einstein like intelligence. He can weave and jump off walls and drink out of the tap. But lordy can he be stupid. Everything he does seems to revolve around his stomach. His reality is food, especially human food. This cat eats and watches TV, he only watches certain shows, all food shows.

The brain of the domesticated cat is about 5 centimeters (2 inches) long and weighs 25-30 grams (0.9 to 1.1 ounces). If a theoretical cat is taken to be 60 cm long with a weight of 3.3 kg, then the brain would be at 0.90% (0.91%) of its total body mass, compared to 2.00% (2.33%) of total body mass in the average human. Within the encephalization quotient proposed by Jerison in 1973, values above 1 are classified big brained, lower than 1 are small brained. The domestic cat is attributed a value of between 1 – 1.71 relative to human value that is 7.44 – 7.8 The largest brain in the cat kingdom are those of the tigers in Java and Bali, of which the largest relative brain size within the pantera is the tigris. It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates. Correlations have been shown between these factors in a number of experiments, however correlation does not imply causation. Most experiments involving the relevance of brain size to intelligence hinge on the assumption that complex behavior requires a complex (and therefore intelligent) brain, however, this connection has not been consistently demonstrated.
The surface area of a cat’s cerebral cortex is approximately 83 cm² whereas the human brain has a surface area of about 2500 cm². A theoretical cat weighing 3,500 grams has a cerebellum weighing 5.3 grams, this 0.17% of the total weight comparible to 4.22% in the human.
Although the House Cat can be really dumb at times, they are just so bloody good looking that I forgive their transgressions and just want to cuddle with the little bugger.
9 de Julio Avenue (or Avenida 9 de Julio, in the local tongue) in downtown Buenos Aires, Argentina, is not just any street. Nine lanes wide, with gardened medians between the opposing flow of traffic, this is the widest street in the world. Only those with a quick pace and long legs will be lucky to get to the other side before the traffic lights at the intersection changes. A pedestrian crossing this street usually requires a few extra minutes and two to three traffic light rotations. 9 de Julio Avenue is only 1 km long but 110 meters wide.
The avenue’s unusual width is because it spans an entire city block, the distance between two streets in the checkerboard pattern used in Buenos Aires. The avenue runs to the west of the Río de la Plata waterfront, from the Retiro district in the north to Constitución station in the south. It has up to seven lanes in each direction and is flanked on either side by parallel streets of two lanes each.
The street runs far in both directions and connects the unique sections of the metropolis. Some of Buenos Aires’ main landmarks can be seen along the way; most notably, the Obelisk, that sits in the middle of 9 de Julio, the original French Embassy, the statue of Don Quixote, the Teatro Colon and the former Ministry of Communications building – the only building that sits on the avenue itself at the intersection with Moreno street.
