Aim for an age range of around 5 months, as suggested by the Feline Advisory Bureau.Kittens are not as set in their ways as adult cats, and often adapt to new things more seamlessly.ince kittens of 5 months have smaller necks than adult cats, look for a collar that is specifically labeled as being for kitten use.

The Julian Day number is the number of days elapsed since noon (12:00) on January 1, 4713 BC The Modified Julian Day number is the number of days since midnight on November 17, 1858 AD (MJD=JD-2400000.5) The Gregorian calendar is used for dates on and after October 15, 1582 AD and the Julian calendar is used before October 4, 1582.
The Gregorian calendar is a minor correction to the Julian. In the Julian calendar every fourth year is a leap year in which February has 29, not 28 days, but in the Gregorian, years divisible by 100 are not leap years unless they are also divisible by 400.n the Julian calendar, any positive year is a leap year if divisible by 4. (Negative years are leap years if the absolute value divided by 4 yields a remainder of 1.) Days are considered to begin at midnight. In the Julian calendar the average year has a length of 365.25 days.
