Every technique yields results that can beinterpreted in more than one way. A UniversalTruth!

However, the subset of interpretations for results obtained with one technique may differ from the subset obtained with another technique.

Breeding and socialising cats

Of those kept as pets in the UK, 8 per cent are pedigree cats.(75 per cent of dogs are pedigree)

Breeding optimally

Breeding for temperament

Socialising

Consequences of inbreeding

Inbred animals are:

Less likely to survive than outbred animals

Less likely to reproduce

Less fertile and have lower birth rates

More likely to have disrupted development

More likely to express genetic disorders

More likely to have reduced immune system function

Sibling with sibling 0.5

Grandfather with granddaughter 0.25

Cousin with cousin 0.125

Coefficient of relatedness

These calculations assume a population of infinite size and previous mating has been at random.

Most cats are much more inbred thantheir pedigrees suggest

A unique feature of domestic cat behaviour

From: Charles Darwin (1872) Expression of the Emotions

“Cat in an affectionate frame of mind”

The cat goddessBastet

The tomb fresco of the sun god Ra cutting off the head of a serpent (from about 1300 BC)

The Ancient Egyptian priests bred cats in enormousnumbers for worshippers at the temples.

In the large cat farms o the day, rapid selection for signalling friendly intent with the tail up may have occurred.
