There's no clear answer to this question since there's no agreed-upon definition of "neurodivergent." Some might say that any animal can be neurodivergent since all animals have unique brains. Others might say that only humans can be neurodivergent because we're the only species that has been studied in depth in this way. Ultimately, it's up to the individual to decide whether or not they believe cats can be neurodivergent.
