My F3 girl is the most devious of my 5 cats, she is also the most loving and affectionate of the bunch. Litter box wise, my F2 twins are the best, my F3 boy, not so much. lmao.
Sure the F2's can be more energetic, and can be quite the handful, though part of that is being only one year old, though my 6 year old F3's can be just as kitten like, at times.
All my cats have their own unique way of demanding love. All tend to follow me around, trip me up, and demand attention. All my SV's are leery of strangers, and take some time to warm up to non family members. The boys will likely not be seen by guest, but will keep an eye out for ya, the girls will allow one to play fetch with them, after the initial hiss, scratch and sniff introductions. lmao while the boys may take days to accept friendship.
All cats seem to have their own unique purrsonality traits that takes a higher accountability than their F generation level, when it come to behavioral and acceptance to others.
There is no guaranty that a F5 will be more sociable than say an F2. The personality, bounding procedure of the individual kitten, and how they develop will be the more telling of the outcome.
