Height and weight and size for a calico cat? The colour of the cat's coat does not depict its overall shape and weight. The average weight of a cat is usually about 8 - 16 pounds. Cats average about 23 - 25cm in height and 46cm in body length, not including the tail.
Calico Cats are not a specific breed of cat but it is pattern of colouring that gives the name. These cats are tri-coloured with patches of white, red or orange and black fur. The calico cats are usually females and this is due to the presence of orange or black colour expressing genes on the X-chromosome. Female cats have two X chromosomes, one X chromosome from the mother which expresses orange colour and another X-chromosome from the father which expresses black colour.
