Django: Can't get models fields to show in template

I can't get the cat name and kitten type from the Cat and Kitten models into the template.

This is my model.py

class Cat(models.Model):
    cat_name = models.CharField(max_length=200)

    def __str__(self):
        return self.cat_name

class Kitten(models.Model):
    cat = models.ForeignKey(Cat, on_delete=models.CASCADE, related_name='kittens')
    kitten_type = models.CharField(max_length=200)

    def __str__(self):
        return self.kitten_type

My views.py

class CatViews(generic.ListView):
    model = Cat
    template_name = 'polls/cats.html'


class CatDetail(generic.DetailView):
    model = Kitten
    template_name = 'polls/kitten.html'

My urls.py


urlpatterns = [
    path('cats/', views.CatViews.as_view(), name='catlist'),
    path('cats/<int:pk>/', views.CatDetail.as_view(), name='catdetail'),
]

And finally, polls/kitten.html

<h3>{{cat.cat_name}}</h3>

{% for kitty in cat.kittens.all %}
    <p>{{ kitty.kitten_type }}</p>
{% endfor %}

The url is working, I'm just not able to display the fields from the models into their respective html elements. What am I missing?

Figured it out. I had to set the CatDetailView to the Cat model, not Kitten model.

The final code: 

class CatDetail(generic.DetailView):
    model = Cat
    template_name = 'polls/kitten.html'

Alter you views.py with the following

class CatViews(generic.ListView):
    model = Cat
    context_object_name = 'cat'
    template_name = 'polls/cats.html'

Alter your polls/kitten.html

<h3>{{cat.cat_name}}</h3>

{% for kitty in cat.kittens.all %}
    <p>{{ kitty.kitten_type }}</p>
{% endfor %}

EDIT

Additionally, alter you CatDetail

class CatDetail(generic.DetailView):
    model = Kitten
    context_object_name = 'kittens'
    template_name = 'polls/kitten.html'

EDIT 2

Alter your polls/kitten.html to this.

<h3>{{cat.cat_name}}</h3>

{% for kitty in cat.catdetail.all %}
    <p>{{ kitty.kitten_type }}</p>
{% endfor %}

class CatViews(generic.ListView):
    model = Cat
    template_name = 'polls/cats.html'
    context_object_name='cat'

And your polls/cats.html would be like,

<h3>{{cat.cat_name}}</h3>

{% for kitty in cat.kittens.all %}
<p>{{ kitty.kitten_type }}</p>
{% endfor %}
