Our kittens leave home earliest at the age of 12 - 14 weeks.
They have been:
Dewormed 3-4 times
Vaccinated twice against Panlevcopenia and Catflu
Registered at SVERAK/FIFE
Chip marked with identification number
Veterinarian health control less than 7 days before delivery,
resulting in a health cerificate for each kitten.
Three years insurance against so called "hidden wrongs", at least in Sweden.
They are socialized and used to people and other cats
