if your friend can not stop at your house, or family member then yes he will be lonely and distructive. your only option, i think, is a cattery where your kitten will be well fed and the tray cleaned and also will recieve fuss and care from the owners of the cattery.

you should now concentrate on visiting some catterys in your area, and asking questions of their owners to find a place for your kitten. i would do this if i were you.
