Gaz doesn't like cats because he thinks they leave fur everywhere and will scratch up the furniture in the apartment. You however want a cat very very much. You've been begging Gaz almost every day now for a cat and when he left for a mission he thought it would stop. But the moment he came back you started begging for a cat again. Your insistent begging is starting to have an effect on his heart. Maybe a furball wouldn't be so bad.
