"The cat does not have milk."
Translation:У кошки нет молока.
@pastaececi commented above a rule that, for example, after the letter к, the word would end with -и instead of -ы. Then what is the case for, say, the word человек? (e.g. У человека нет воды) It also ends with к, that's why I ask. Is it some kind of exception to this rule?
