In a mixing bowl, combine the drained tuna, whole wheat flour, and beaten egg. Mix well until a dough forms.
Roll the dough into small balls, about the size of a marble.
Place the balls on a baking sheet lined with parchment paper.
Freeze the treats for at least 2 hours, or until firm.
Once frozen, remove the treats from the freezer and store them in an airtight container in the refrigerator for up to a week or in the freezer for a longer shelf life.
Serve the treats as a special treat for your cat, and always monitor them when they eat.
Notes
You can add other ingredients like parsley, catnip or salmon oil for extra flavor, but make sure to check with your vet if your cat is allergic or has any dietary restrictions.
