That's good advice from Caspersmum. Unfortunately, when we got Talon at 9 weeks, she had come to us with her wings clipped. We kept them clipped as we didn't know what would be best for her. She is now 19 months and is able to fly if she wants to. She might fly 2-3 times a day if that, and only to come see where we are.
In the beginning, she would try to fly, she would just fly down, she wasn't able to stay up. We were lucky, as she was careful not to get hurt. I prefer her not to be clipped now because if she lands on the floor, i'm afraid one of our 2 cats would attack her. In fact I know they would if I wasn't in the same room.
I think it's a matter of preference and what works best for you & your situation. I would worry when they are young about getting hurt.
