Mutations

Mutations
Whilst breeding during normal gameplay, mutations may occur in the genetics of offspring. These are often random and consequently fairly rare, yet are arguably more common when two pets have been the subject of in-breeding. Mutations shall cause your pets to have different features-most commonly extreme coat colours.

Examples of Mutations
Mutations mainly are seen in the form of extreme coat colours. Most commonly, if a puppy or a kitten has mutated, it's coat colour may be either white, grey or black, despite their parents' pelt colour not including any one of these.
