Cottage food operations do not have licenses... You are legally allowed to have a pet under the regulations as well... You cannot make anything that requires a fridge though... All goods should also be labeled as made in a home kitchen...
There is a home licensed kitchen that allows you to make food that requires a fridge... you are not allowed to have pets... your kitchen must pass an inspection... and there is a $10 fee to the department of agriculture...
That is based on state laws... each county has their own regulations that may vary...
