However, cats should have only one of two undertones: gold or silver.Ĭats with golden undertones can be tipped with any of the solid colors we mentioned above-almost, at least. There are many different color combinations. These felines end up with markings and have a shaded appearance due to the difference in coloration throughout their coat. Some Oriental Shorthair cats are mostly solidly colored but with extra undercoat shades. However, because many of these patterns are extremely similar across the different colors, we’re going to explain them briefly-not list out every possible combination. ![]() It’s the combination of all these patterns and all the available colors that give the breed so many different possibilities. The 5 Oriental Shorthair Coat PatternsĪll the colors above can appear in a range of different patterns, too. This feline shouldn’t have any other markings, or it would fall into a different color category. Rarely, you can find solid white Oriental Shorthair cats. Markings are common with this coat color, but solid-colored cats exist, too. It’s not understood why the color is evolutive, and why kittens can still produce black hairs.A post shared by Malachi And Ron (&Family □□) felines are a darker version of cream with more red overtones. However, it seems that red amber cats are light-colored looking almost like a red silver tabby. The orange gene is epistatic to the amber, meaning that on a red cat the amber won’t have any effect. That’s why amber solid cats have ghost tabby markings, even if they are not tabby. This means that–even if a cat is a/a (aka solid or non-tabby)–the expression of this gene will be blocked by the amber one. Empirically, it seems that amber carriers generally have a warm coat color.įinally, to explain the phenomena of the black nose in amber solid cats, the gene extension is epistatic over the agouti gene. Non-amber cats are either E/E or E/e.Ĭats having one copy of the e locus (E/e) are called amber carriers, as they have a 50% chance to transmit the amber gene to their offspring. So, an amber cat needs to be homozygous for the allele e (e/e). The dominant allele "E" gives black pigments and the recessive allele "e" gives yellow pigments. To put it simply, in the case of amber cats, this receptor is mutated and, so, it can’t produce black pigments, producing yellow pigments instead. The amber color is caused by the gene called Extension which is coding the melanocortin-1-receptor, which is essential to produce black pigments on the hair. Here are the descriptions of the 4 main variations of the amber color.Ī blue amber blotched tabby in different lightning from Genetic Because of this, amber solid cats are often called black noses. The amber effect applies only to the hair and not the skin: a black amber cat will have dark paw pads.Īmber solid cats (aka non-agouti) have a very particular look as they appear tabby but with a dark nose. The effect of amber will depend on the base color: black amber cats generally have a hot red color, while blue amber (also called light amber) often have a more peach/cream color. The previous articles in the series cover:Īmber is a coat effect that transforms black hair into yellow hair, which gives amber cats generally a warm golden color. Note: Before reading this article, I recommend you to read the articles of the first series on basic cat coat colors: some of the genetic explanations will be useful to understand this article. ![]() As we will see in the article, amber is specific to Norwegian Forest cats and I will explain what are its properties, its history, and the genetics that make it happen. I will start with not just any color, but the one of my cats Néline and Praline: the amber color. It is now time to cover the breed-specific colors. In a previous series of articles, I presented all the basic cat coat colors.
