Why multiple inheritance is bad?

I'm not against multiple inheritance. Anything can be a tool in the right hands, and multiple inheritance is a such tool. But it is common question: why multiple inheritance is not suitable for most situations? And really it is not very good. Almost any problem could be solved using single inheritance, interfaces or composition. Many languages deny multiple inheritance, and here is my point of view on this problem.

Imagine, we have two classes "cat" and "duck" :)

Tip: analyze .net stack and heap

Tip: find memory leaks in .net application

Sometimes we face some nasty problems, while working with managed code. And one of them is memory leak. When you see in task manager, that an application slowly (or rapidly) consumes precious memory, it means that garbage collector can't release some resources, allocated in code. Sometimes it is easy to find the weak spot, sometimes it is not. Memory leak can be represented by something like holding the reference to managed object longer, than it's needed, or not releasing unmanaged resources.
