When you reserve a kitten you can give him a new name. The only requirement is that the name
must be named on the letter of the litter. On the website, after your reservation, the name will have a new and an old(preliminary) name.
For example, before the kitten's reservation, his name was: "Golden Britain's Aurora" and after the reservation "Golden Britain's Alisa-Aurora". Her short name is "Alisa". The contract will contain "Golden Britain's Alisa-Aurora".
