* It/its: This is the most common and neutral pronoun for snakes, as they are not typically considered male or female in everyday language.
* He/him/his/himself: This is used if you know the snake is male.
* She/her/hers/herself: This is used if you know the snake is female.
Important Note: While snakes are male or female, it's often difficult to determine the sex without professional examination, so "it" is the safest bet unless you have specific knowledge.
