40 cat years
A ten year old cat's mass is most likely to be around 6 kilograms, as 6 grams would be extremely lightweight for a cat of that age and size.
I have included a link to a website that will calculate your cat's age for you.
6 WEEKS
It probably depends on the twelve year old. Are they mature? Have they taken care of other kids?
it depends what breed they are and how long they have lived in the same family

40. It is believed that for every human year a cat year is 5.
HI! I am also 11 year old. Well, you obviously can't take care of a 10 year old brother but you can take care of a 6 year old and 5 year old. Its a bit hard but if they are calm enough, its easy as a pie!! Good luck and hope they wont get too naughty!
Most places would not think anything about that. A 16 year old is considered old enough to take care of a child.
