Our kittens are not allowed to go to the garden during the three or four months they are living with us, so that they would not miss it when they are to live in an apartment with their new owners. Bengals can live happily in an apartment, expecially if thy have another cat to keep them company. They need a scratching post, litter box, fresh water, quality cat food and much play and cuddle time with their people.
Free running cats live dangerously. They can be stolen or run over. If you live in a very quiet area and want to try it, you should keep the kitten in the house as long as possible, at least six months to one year, before you let him out. Older cats are more careful outside the house and generally live longer than young kittens.
