Detailed LOOF statistics per breed

LOOF offers you statistics concerning:

• kittens and litters (number of pedigrees per year, size of litters, months of birth, ...)
• breeding cats (number of active studs/queens, number of kittens per stud/queen, age when breeding, inbreeding coefficient, ...
• breeders (number of breeders sorted out by number of litters produced per year, ...)

These statistics cover 16 years, from 2003 to 2019 included and were updated based on the data known up to December 31st, 2019.

A full set of these statistics is published here, both for all breed cats (visible on this page and downloadable in pdf format) as well as for each breed group where more than 200 pedigrees were generated between 2003 and 2019:

• Abyssinian/Somali
• Asian/English Burmese/Burmilla
• Bengal
• Birman
• Bombay/American Burmese
• British shorthair/longhair

Kittens and Litters Statistics, regardless of the breed

Number of registrations per year

(years refer to the pedigree number or RF registration certificate, the kittens who have already bred are in orange)

Litter size analysis

(along the x axis, number of kittens per litter; along the y axis, corresponding number of litters)

Which corresponds to a mean litter size (registered with LOOF since 2003) of 3.27 kittens
(3.49 kittens for litters born during the last two years)

Proportion males vs females (computation taking into account pedigrees over the whole period) : males : 51.1%, females : 48.9%.

Spread of litter birth dates month per month

(along the x axis, month during which the litter was born - along the y axis corresponding number of litters)

Inbreeding coefficient for LOOF-registered kittens

(along the x axis, inbreeding coefficient of kittens ; along the y axis, number of kittens with this inbreeding coefficient)
NB: the computation only includes "traceable" inbreeding, i.e. coming from known ancestors,
the inbreeding coefficient of unknown ancestors being set to 0

The computation takes into account all ancestors known by LOOF
This knowledge varies between cats but its mean on all litters is equivalent to the knowledge of 8 complete generations.

Mean per litter, computed over 158580 litters born since 2003: 3.16 % (mean per kitten, computed over 519314 kittens: 2.91 %)

Percentage of kitttens having a traceable inbreeding coefficient between

• 0 and 1,99 % : 69.2 %
• 2 and 9,99 % : 22.7 %
• 10 and 19,99 % : 5.2 %
• 20 and 29,99 % : 2.5 %
• 30 and 50 % : 0.4 %

Stud/queen statistics

Studs

8905 studs having had at least one litter during the last two years
(1701 studs contribute for more than half of the kittens, and 4217 studs contribute for more than 80 % of the kittens)

Analysis of the number of kittens per stud during the last 24 months:

(along the x axis, number of kittens per stud - along the y axis, number of studs concerned)

Spread of active studs according to their age when their kittens are born

(one bar per trimester, the x-axis is labelled with the age in full years)

Queens

18195 females having had at least one litter during the last two years.
(ratio of 2.0 active queens per active stud).
(4836 females contribute for more than half of the kittens, and 10449 females contribute for more than 80 % of the kittens)

Analysis of the number of kittens per queen during the last 24 months:

(along the x axis, number of kittens per female - along the y axis, number of corresponding queens)

Spread of queens according to their age upon delivery

(one bar per trimester, the x-axis is labelled with the age in full years)

Main countries of origin of imported cats

(this list includes the top 15 countries of origin of cats registered with LOOF, with the number of males and females imported during the last two years)

Breeders' Statistics

21993 breeders have had at least one litter since 2003
8089 breeders have registered at least one litter born during the last 24 months.

Respective number of breeders having registered one single litter (red), between 2 and 4 litters (orange),
between 5 and 9 litters (dark yellow), or at least 10 litters during the year (pale yellow)
