Najafi Q&A: Killing Animals

Your Eminence, there are narrations that encourage killing the lizard. It has also been recommended to perform ghusl (ritual purification) after killing it. We notice that many people kill it on the grounds that its presence is repulsive and frightens children and women, especially since it is often found in bathrooms. What is your opinion?

Is it permissible to kill a cat which is in the house by poisoning it with the food due to the intimidation it causes to the children and the dirt to the house?
