Titles - Different in every organization
Every organization has its own show system, and therefore also the titles are very different.
| There is no contract between the organizations that titles are recognized amongst the various organizations. That means, if a cat wants to receive the title Int.Ch. in FIFe for example, the Champion title of WCF is not recognized by FIFe, it must first receive the champion title and then the title Int.Ch. |
| WCF is here somewhat more open, as titles from several organizations are recognized... |
03/2007: In breeding: Pedigree
What is a pedigree?
The cat has a name, mostly consisting of a first name and a cattery name.
Each organization registers cattery names (quasi the family
name of the cat) by its own. There is no central registration of
cattery names for all organizations; thus the same cattery name may
exist in different organizations for different breeders...

Disorder in the eye lids
Enrolled eye lid
Entropion
The eye lids are rolled inwards, which causes a permanent irritation of the
eye ball by the eye lashes.
Ectropion
Eversion of the eye lids, the eye lids are rolled outwards.
Eye lids where the edges are tuned inwards or outwards are likely to be seen
in so called extreme breeds, for example in breeds with very short faces,
like Persians and Exotic.

Pet passport - Microchip - Health certificate
The EU-regulation 998/2003 from 26.5.2003 rules the travelling, crossing the border and the import of pets.
Each cat must have:
| EU-pet passport: §3b and §17 section 2 |
| Microchip: § 4 |
| When the cat comes from a country listed in Appendix Part C and Appendix Part B Section 2, it also must have a health certificate. |
What does the cat see?
The cat is a nocturnal animal, thus the amount of rods (Retina: No. 2) is much higher than that of the cones (Retina: No 3).
Vision field
The Vision field of a cat (200° in total) is much less when
compared to preys, because the cat is a predator (9 lens) and has to
look into forward and downward direction when hunting. Her eyes are
forward-faced and relatively large. The vision is, compared to
humans (180° in total), larger. Horses have a vision of 305°m dogs

The cell and the DNA
The DNA consists of two strands, called double helix, which wind
clock-wise (to the right) around an imaginary axis.
Helix = the ladder.
