Was fragst du, soll es deutsch sein oder nicht, weil ich verwirrt bin.
Answer:
The answer would be: '<em>Wir haben eine Katze</em>'
Explanation:
Cat in German is 'Katze' which means it is a female but we normally use the word <em>'Katze' </em>when we don't know the gender.
If it was specifically a male cat we would use the word '<em>Kater</em>' and would say: '<em>Wir haben einen Kater</em>'.
