Think of the top 10 concepts that could be associated with a cat, such as cat as a pet, or taking care of the pet cat like feeding it or providing veterinary services. But these concepts should be pretty specific to cats, the concepts should not apply to humans or the world in general outside of cat related topics. 

For each concept, think of the top 10 unique related words that would be associated with that concept. Only use single words, not phrases. Return one comma separated list of all the related words. Don't include the topic concepts in the list. All lowercase results. All unique, no duplicates.

Omit words and concepts that could also apply to humans or things in general. The words should only apply to cats and cat-related things.

Return the list formatted as a JSON array.
