Em has had a sore neck and top of her shoulders this past week. Despite a full massage to fix it, it continues to annoy her. Last night I made her a custom kitty neck heat pack! Worked perfectly and smells divine with the blend of lavender included... Has individual sections to keep the contents evenly distributed, tucked inside a removable and washable cover. Tipping the scales at 1.5kgs, it adds the weight needed to relax muscles. Em is very happy!
