Forum:Attack own monsters?

My son and I have been going back and forth on this issue. Please help us settle it.

Let's say you have 2 monsters on the field: Giant Rat and another with 1600 ATK. Can you attack Giant Rat with your own 1600 ATK monster to activate Rat's effect?

Thanks in advance for your help.
