Normally when I go out to work, I have to keep them inside the house. But, when I came back, I will let them out and I will watch them . They love it. After 1 @ 2 hours I will call them back. At least bagi mereka rasa nikmat being free. I make it as a routine. Don't worry. Normally, they won"t go far. They know their house. Their sense of directions is very strong. Susah org nak tangkap coz they are very cunning and not friendly to strangers.
