unexpected class 新手求助

这是小甲鱼上课用的一段代码，但是总是提示我unexpected class'Dog'

#include <iostream>
#include <string>

class Pet
{
public:
        Pet(std::string theName);
        ~Pet();

        static int getCount();

protected:
        std::string name;

private:
        static int count;
}

class Dog:public Pet
{
public:
        Dog(std::string theName);
};

class Cat:public Pet
{
public:
        Dog(std::string theName);
};

int Pet::count=0;

Pet::Pet(std::string theName)
{
name=theName;
}

Pet::~Pet()
{
        count--;
        std::cout<<name<<"挂掉了\n";
}

int Pet::getCount()
{
return count;
}

Dog::Dog(std::string theName):Pet(theName)
{
}

Cat::Cat(std::string theName):Pet(theName)
{
}

int main()
{
Dog dog("Tom");
Cat cat("Terry");

std::cout<<"\n已经诞生了"<<Pet::getCount()<<"zhichongwu\n\n";
{
        Dog dog2("tom 2");
        Cat cat2("jerry 2");
std::cout<<"\n现在呢，已经诞生了"<<Pet::getCount()<<"只宠物\n\n";
}

std::cout<<"\nAnd you're back to"<<Pet::getCount()<<"Pets!\n\n";

return 0;
}

class Cat:public Pet
{
public:
         Dog(std::string theName);//应该是Cat(std::string theName)；
};

class Cat:public Pet
{
public:


这个已经改了 但是还是不对 不知道为什么

pet 类结束少一个“;”，再把上次跟你说的dog改成cat，我用的vs2015 运行成功，还有问题的话你最好把错误的提示截图一下

这个就是我运行的


#include <iostream>
#include <string>

class Pet
{
        public:
         Pet(std::string theName);
         ~Pet();

         static int getCount();

        protected:
         std::string name;

        private:
         static int count;
};

class Dog:public Pet
{
        public:
         Dog(std::string theName);
};

class Cat:public Pet
{
        public:
         Cat(std::string theName);
};

int Pet::count=0;

Pet::Pet(std::string theName)
{
name=theName;
}

Pet::~Pet()
{
         count--;
         std::cout<<name<<"挂掉了\n";
}

int Pet::getCount()
{
return count;
}

Dog::Dog(std::string theName):Pet(theName)
{
}

Cat::Cat(std::string theName):Pet(theName)
{
}

int main()
{
Dog dog("Tom");
Cat cat("Terry");

std::cout<<"\n已经诞生了"<<Pet::getCount()<<"zhichongwu\n\n";
{
         Dog dog2("tom 2");
         Cat cat2("jerry 2");
std::cout<<"\n现在呢，已经诞生了"<<Pet::getCount()<<"只宠物\n\n";
}

std::cout<<"\nAnd you're back to"<<Pet::getCount()<<"Pets!\n\n";

return 0;
