Why Are Sphynx Cats Bald?

Why are Sphynx cats bald?

What is a Sphynx cat?

The Sphynx cat is described as hairless, although that is not entirely true as it actually has short, downy hair that feels like chamois. The breed originated in Toronto, Canada in 1966 when a black and white tuxedo called Elizabeth gave birth to a hairless male kitten named Prune. Prune was mated back to Elizabeth, and this mating produced more bald kittens.

Hairless cats had occurred prior to that but quickly vanished. Several other hairless breeds are recognised in the cat fancy today including the Peterbald, Don Sphynx, Bambino, Elf, Ukrainian Levkoy and Dwelf. Most of these breeds are man-made Sphynx crosses, such as the Bambino, which is a cross between a Munchkin and Sphynx. The Don Sphynx occurred due to a spontaneous mutation which is different to the Sphynx mutation.

Can Kittens Be Identical Twins?

Can kittens be identical twins

Can two cats be identical twins?

Identical or monozygotic twins are possible in kittens, but rare. Almost all kittens in a litter are not identical, even if they have the same physical appearance.

What are identical twins?

Identical (monozygotic) twins occur when a fertilised egg splits in two during early development resulting in two kittens who share the same DNA. This differs from non-identical (dizygotic twins) who have their own unique DNA. The worldwide incidence of identical twin births in humans is 3 – 4 per 1,000 births. We don’t tend to refer to kittens as twins, triplets, etc, in animals who give birth to multiple offspring, instead, they’re known as littermates.

What is Klinefelter syndrome in cats?

What is Klinefelter syndrome?

Also known as XXY syndrome, Klinefelter syndrome (KS) is a sex chromosome condition that occurs when a male kitten is born with an extra X chromosome. Klinefelter syndrome is a type of trisomy, which is a chromosomal condition characterised by an additional chromosome. Down syndrome is the most well-known trisomy in humans that is caused by a third copy of chromosome 21.

A tortoiseshell cat is a cat with a coat colour made up of mottled patches of black, chocolate or grey along with red or cream. This unusual coat pattern is sex-linked and is almost exclusively found in female cats.

The most common colour combination is black and red, which consists of almost equal amounts of black to red. In some cats, there will be more red than black, which is known as a reverse tortie.

What is a dilute tortie cat?

Also known as a muted tortie, a dilute tortie is a type of coat colour and pattern which consists of grey and cream markings.

This striking coat pattern is the dilute form of the more traditional black and red (orange) tortie pattern. Tortoiseshell almost exclusively occurs in female cats as the orange gene is located on the X chromosome, as the male (XY) only inherits one copy of the X chromosome he will either be orange or non-orange. As a female cat (XX) has two X chromosomes, if she inherits one copy of the orange gene, and one copy of black, she will be tortoiseshell. The dilute gene changes black and red to grey and cream.

Grey Cats – Breeds, Genes and Inheritance

All about grey cats

Also referred to as blue or Maltese, grey is a common coat colour in both purebred and domestic cats. Grey is the dilute form of black, caused by the aptly named dilution gene which is caused by a single base deletion 1 bp in the melanophilin (MLPH) gene. This gene provides instructions for making melanophilin, a carrier protein that is found in pigment-producing melanocytes. Melanophilin is essential for the even distribution, transport, and translocation of melanin (pigment granules). Menalocytes are specialised cells that contain organelles known as melanosomes. Melanosomes synthesise, store and transport melanin out of the cell via the dendrites to neighbouring keratinocytes (keratin producing cells).
