请问能帮忙完善下面的圈猫程序吗？

}

每次按下功能键（如Enter键）时就将一只猫放在一个围栏里，这个围栏可以容纳7只猫。每只猫都是一个类Cat的实例化对象，而该类是在cat.h中定义的。每个猫对象在动态地实例化时，都会随机地赋予一种皮毛颜色[如black(黑色)、gray(灰色)或者brown(棕色)等]，还将被随机地赋予一种眼睛映射[如green(绿色)、blue(蓝色)或者brown(棕色)等]以及毛长[short(短)和long(长)]

在将猫放在围栏中时，某些组合会使其发生争斗。例如，如果灰猫的数量超过棕色猫的数量，灰猫就会与棕色猫打架。如果在围栏里有一只黑毛、棕色眼睛的猫，同时还有至少一只黑色的绿眼睛猫和至少一只黑色蓝眼睛猫，也会发生争斗。编写一段名为check的非成员函数确定猫之间是否会打架。
