We are proud to introduce Felpati Gatti Elvis, an exceptional British Shorthair male joining Vlastar Lux Cattery as a future stud and a cornerstone of our next chapter: a carefully designed golden cinnamon & fawn program.

Elvis is not only visually breathtaking — he is genetically fascinating. His color is a rare, highly desirable composition that combines fawn(the dilute expression of cinnamon), golden wideband shading, and bicolor white in one harmonious phenotype. This combination is uncommon even in advanced golden programs, and it opens exciting opportunities for breeders who understand and value feline color genetics.

🌟 “Bloodline story”

Line focus & origin

Elvis comes from a Czech breeding program (Felpati Gatti, CZ) with strong emphasis on golden shaded/shell expression and refined British type.

🧬 Genetic Color Formula — Felpati Gatti Elvis (BRI py 11 03)

Base pigment: cinnamon-series (TYRP1) B-locus: b¹/b¹

Dilution: expressed D-locus: d/d → fawn

Orange locus: non-red (male) O-locus: XoY

White spotting: bicolor S-locus: Ws/w or Ws/Ws

Golden shaded phenotype:

Agouti required A-locus: A/-

Non-silver background I-locus: i/i

Wideband / rufousing selection polygenic (WB-type)

Shading level EMS 11 (shaded)

📌 Notes for advanced breeders

b¹/b¹ (cinnamon homozygous) + d/d (dilution) → fawn
This follows TYRP1 and MLPH interactions described in breeder and laboratory genetics resources.
A/- + wideband (WB) → golden series phenotype
Golden is the non‑silver equivalent of wideband tipping.
Ws/w explains the bicolor pattern in EMS 03.
EMS 11 defines the shaded tipping percentage (phenotypic classification).

These elements together produce the py 11 03 phenotype:
fawn + golden + shaded + bicolor.

B‑locus (cinnamon → fawn) + D‑locus (dilution) + S‑locus (white spotting / bicolor) + Golden/Shaded (EMS tipping + wideband phenotype), and a bottom block that ties it to Elvis: BRI py 11 03.

Parents:

Father: Felpatigatti Golden Maserati, BRI cu (cy) 12, lilac golden shell

Mother: Felpatigatti Golden Wanessa, BLH pu (py) 11 03, fawn golden shaded bicolor

🏆 Conformation & Character: British type you can feel 💂

Elvis is built in full accordance with the British Shorthair male standard look: a compact cobby body, short strong legs, broad round head, and small, well‑placed ears that enhance the classic “teddy bear” expression.
His overall balance is impressive: masculine without coarseness, powerful without heaviness — a future stud with true presence.

Just as important: his temperament is exceptional. Elvis is confident, affectionate, and very stable in daily life — in great contact with people, while remaining mature and composed. This is exactly the kind of character we want to fix in a long‑term breeding program: predictable, intelligent, and easy to live with.

🧬 Genetics Corner: for smart breeders

1) What his EMS code actually tells

FIFe’s EMS (Easy Mind System) is a standardized way to describe appearance (phenotype), not a direct genotype description.
For Elvis: [fifeweb.org]

p = fawn [fifeweb.org]
y = golden [fifeweb.org]
11 = shaded [fifeweb.org], [EMS – Doub…e Forgeron]
03 = bicolor (white spotting) [EMS – Doub…e Forgeron]

So BRI py 11 03 = British Shorthair fawn golden shaded bicolor. [fifeweb.org], [EMS – Doub…e Forgeron]

2) Why “fawn” is special: cinnamon + dilution (B‑locus + D‑locus)

In modern coat‑color genetics, cinnamon is produced by a recessive variant at the TYRP1 (Brown) gene / B‑locus, where the allelic series is commonly described as B > b > b1 (with the most recessive producing cinnamon).
When dilution (dd) is added, cinnamon becomes fawn (the dilute version of cinnamon). [langfordvets.co.uk], [laboklin.co.uk] [sparrows-garden.com], [langfordvets.co.uk]

Breeder takeaway: to consistently produce fawn, you need partners that are dilute (dd) or at least carry dilution (Dd) — otherwise the cinnamon/fawn potential stays hidden in offspring. [sparrows-garden.com], [langfordvets.co.uk]

3) Golden shaded: wideband + agouti‑based banding, with “tipping depth” described by EMS

Golden shaded cats get their luminous warm undercoat from agouti banding combined with wideband‑type effects (often discussed as polygenic selection in breeding).
The EMS “11 shaded” describes the extent of tipping/shading on the hair (more shading than shell/chinchilla “12”), which is how registries classify the look. [INHIBITOR…MESSYBEAST], [belleayr.com] [EMS – Doub…e Forgeron], [fifeweb.org]

4) Bicolor: the white spotting gene (S)

Bicolor patterning is caused by white spotting variants, which are inherited as autosomal dominant traits (one copy is enough to express some degree of white).
This is why Elvis’ “03” is not just cosmetic — it’s a heritable pattern component that can be strategically used to produce bicolor golden kittens when paired thoughtfully. [vgl.ucdavis.edu] [vgl.ucdavis.edu], [EMS – Doub…e Forgeron]

**🌟 Why Elvis’ color combination is rare and valuable**

Elvis combines multiple “specialty” elements in one cat:

Fawn (p) — requires cinnamon genetics plus dilution to be visible. [langfordvets.co.uk], [sparrows-garden.com]
Golden (y) — a golden program trait described in EMS and refined by selective breeding. [fifeweb.org], [INHIBITOR…MESSYBEAST]
Shaded (11) — specific tipping depth classification. [EMS – Doub…e Forgeron]
Bicolor (03) — white spotting inheritance. [vgl.ucdavis.edu], [EMS – Doub…e Forgeron]

Getting all four together with correct British type and temperament is exactly why advanced breeders pay attention: it’s not only beautiful — it’s a valuable genetic tool.

🚀 Our Vision: a New Golden Cinnamon & Fawn Line at Vlastar Lux

With Elvis, we begin a new color direction in our cattery:
✅ golden cinnamon (oy … in EMS terms) and
✅ golden fawn (py …),
with an emphasis on British type, health, and predictable temperament.

For breeders who like clarity, this program benefits from DNA verification of key loci (especially B‑locus/TYRP1 for cinnamon and D‑locus for dilution) — this is how serious programs reduce “surprises” and stabilize rare colors over generations. [langfordvets.co.uk], [sparrows-garden.com], [laboklin.co.uk]

🧩 Suggested “Breeder Notes” section

Breeder notes:
Elvis represents a rare combination of fawn (dilute cinnamon), golden wideband shading, and bicolor white spotting.
He is an ideal foundation male for breeders interested in developing or strengthening golden cinnamon/fawn lines, especially when paired with queens carrying compatible dilution and brown‑series genetics.

What’s inside: a quick guide for breeder 🧑‍🏫 readers 👩‍🏫

B‑locus / TYRP1 (brown series): simplified dominance series and why cinnamon is recessive (needs two copies to show).
D‑locus / dilution: dilution is recessive, and d/d is required to express dilute phenotypes (like fawn).
S‑locus (white spotting): autosomal dominant white spotting; and how EMS “03” corresponds to bicolor.
Golden/Shaded: explains that “golden” in EMS is a phenotype label, and “11 shaded / 12 shell” are tipping depth registry descriptors, while wideband/rufousing selection is typically treated as polygenic in breeding practice.
Example build: explicitly shows how py 11 03 is interpreted in “breeder language.”

The EMS pattern codes and the meaning of 03 (bicolor) and 11 (shaded) come directly from EMS reference descriptions.
White spotting as a dominant inherited trait is summarized in veterinary genetics testing notes.
The cinnamon → fawn relationship via dilution is consistent with standard dilution explanations used in cat genetics education. [us-prod.as…rosoft.com], [us-prod.as…rosoft.com] [EMS – Doub…e Forgeron] [fifeweb.org], [vgl.ucdavis.edu]

Genotype (phenotype = py 11 03: fawn golden shaded bicolor)

D-locus (Dilution): d/d (fully dilute — cinnamon + dd = fawn)

O-locus (Orange, X-linked): XoY (non-red male)

S-locus (White spotting): Ws/w (white spotting present → bicolor EMS 03)

Tabby locus (pattern base): Ta/T- or T/- (agouti-based pattern background; exact allele not visible in EMS)

Wideband / Rufousing: WB/– (polygenic wideband expression for golden)

Tipping level (phenotype): EMS 11 (shaded; ~1/4 hair length tipped — registry descriptor)
