unexpected class error

[PRW56]

well this is word for word one of the examples from my c++ book, I have no idea what the error means, the error is: error: new types may not be defined in a return type. it occurs on line 3

here is code:

#include <iostream>

class Cat //error occurs here
{
    public:
        Cat(int initialAge);
        ~Cat();
        int getAge();
        void setAge(int age);
        void meow();
    private:
        int cAge;
}
Cat::Cat(int initialAge)
{
    cAge = initialAge;
}
Cat::~Cat() {}
int Cat::getAge()
{
    return cAge;
}
void Cat::setAge(int age)
{
    cAge = age;
}
void Cat::meow()
{
    std::cout<<"Meow.\n";
}
int main()
{
    using namespace std;
    Cat frisky(5);
    frisky.meow();
    cout<<"Frisky is a cat who is "<<frisky.getAge()<<" years old.\n";
    frisky.meow();
    return 0;
}
