I assume the breed is less wanting of lap time or was that just my cat?
Mine went in phases. From 12 wks to about 5-6 months -- always on lap. Six months to about 1-1.5 years -- too proud to be seen on mom's lap; 2 years and on -- must always be on my lap.
Good luck with your search for kittens (or as we affectionately call them "shittens") and keep us posted. Those of us who have reached our limit on cats live vicariously through others.
