Cat Registration what is SBT?
When you see the initial, SBT associated with the cat’s pedigree what does it signify. Those initials stand for Stud Book Traditional. All SBTs are classified as purebred cats. To be eligible for pure breed status, the cat must be a product of three consecutive mating within the breed. For a cat to be a SBT both parents’ registration status must be either C or SBT. The letter designation is based on parent closest to outcross equals the sequence of letter following, example A=B, B=C, C=SBT.
Example of breeding to achieve SBT status
- F1A Savannah Female mated to Savannah Male (F5) = F2 SV female (AON or AOP)
- F2B SV bred to another savannah male (F5) = F3 SV Female. (BON or BOP)
- F3C SV female bred to Savannah male (F5) = F4 Kitten. (CON or COP)
- The kitten(s) from # 3 mating is an SBT, purebred Savannah (SBT)
Savannah Males are not fertile until the 5th generations.
What’s on the registration? How is the information arrived at? This is an example of a registration with an explanation of each recorded input. The registration number consists of three letters, followed by a space then 6 numbers, another space with 3 extra numbers. Three letters are the pure-breed grade. The first numbers (6) are the date of birth of the cat, the second set of numbers (3) is the order of registration was processed on the given day.
