Question

Forms.py is connected with

from .views import *

class CatForm(forms.ModelForm):
    class Meta:
        model = Cat
        fields = ['title', 'slug']


    def clean_slug(self):
        new_slug = self.cleaned_data['slug'].lower()


        if new_slug == 'create':
            raise ValidationError('Slug may not be "creare" ')
        if Cat.objects.filter(slug__iexact=new_slug).count():
            raise ValidationError('Slug must be unique')
        return new_slug

class LinkForm(forms.ModelForm):
    class Meta:
        model = Link
        fields = ['title','slug', 'content', 'cats', 'user']
        exclude = ['user']

    def __init__(self, *args, **kwargs):
            super().__init__(*args, **kwargs)
            self.fields['cats'].queryset = Cat.objects.filter(user=self.initial['user'])

Answer 1

The form has no initial values, so there is no key userin self.initialit.
