Put on a sweater. Don’t have one, cause cat is not a “wear sweater” kind of cat? C’mon, even BC has it! It warms your chest.
Drink hot chocolate milk…eat a bowl of warm soup.
Rub chest and back with warm balsam.
Just stay in bed, don’t go outside. Rest and sleep well.
Stay out of your daily activities.
Lovesick? Well, that is something cat knows what to do…
