Cat intelligence
The brain of the domesticated cat is about long, and weighs . If a typical cat is taken to be long with a weight of , then the brain would be at 0.91% of its total body mass, compared to 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, while values 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 brains in the Felidae family are those of the tigers in Java and Bali, of which the largest relative brain size within the "panthera" 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.
Snowshoe cat
The ear size ranges from medium to medium-large with slightly rounded tips. The head may be triangular, however can be an "applehead" shape with a traditional cat look. The short-haired coat consists of solid and white patterns. Points (ears, tail, face-mask and sometimes legs) are solid black-based colors. White patterns vary, typically falling along the face, chest, stomach, and paws. The body is an even coloration, subtle shading to point color on back, shoulders and hips; toning to a lighter shade near chest and stomach. Paw pads may be white, point color, flesh tone, or mottled. Their color will darken with age, even to the point of turning a chocolate brown shade. In purebreds, the eyes are always blue. The tail is medium-sized. Snowshoe cats come in blue, lilac, lynx, fawn, chocolate, and seal points. The Snowshoe is a medium-large cat and longer length wise than many cats, with many males reaching 14  lbs or more.
