Generic Operator Overloading

Is it possible to make a generic overloaded operator in a class or interface?
[EDIT]It gives me an error now.

Code:

 public static Cat<T> operator +(Cat<T> cat, Cat<T> cat2)
    {
        return (new Cat<T>(cat.name + cat2.name, 0, 1));
    }

[/EDIT]

Code:

class Cat<T>
{
    string name;
    T age;
    T weight;

    public Cat(string its_name, T its_age, T its_weight)
    {
        name = its_name;
        age = its_age;
        weight = its_weight;

    }

    public void Wash()
    {
        Console.WriteLine("Washed successfuly.");

    }

    public Cat<T> Marry(Cat<T> cat)
    {
        return (this + cat);


    }

    public static Cat<T> operator +(Cat<T> cat, Cat<T> cat2)
    {
        return (new Cat<T>(cat.name + cat2.name, 0, 1));
    }




    public T Age
    {
        get { return age; }
    }

    public T Weight
    {
        get { return weight; }
    }


    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    public override string ToString()
    {
        return "Cat Name: " + name;
    }

    public override bool Equals(object obj)
    {
        return base.Equals(obj);
    }

    public override int GetHashCode()
    {
        return base.GetHashCode() + age - weight;
    }

    ~Cat()
    {

        Console.WriteLine("{0} died.", name);
    }


}
