Cats lern more at a younger age than they do when they are older, that is why one teaches a cat not to scratch furniture when they are little, and not leaving it till they are older.
The actual learning age is up to around 10 weeks old. Form a behavourist point of view so do you let them out at this age?
And no I would I mean, your not suggesting you leave a kitten at home by himself are you? Would you do that with a child?

rolleyes:
No I woulnd leave a single kitten on its own all day.
Like I have said I have picked up too many taken by the road, so I rather be ott than be sorry.
