Feliway failed me with my Hima so I’m looking for another option to make the car trip less stressful for her. She totally reacts to matatabi powder but of course it’s with hyperactivity / playfulness. Has anyone tried that or catnip in the carrier? I’m hoping it could make the trip less stressful but also worried if she still gets scared, with the matatabi effect on top of it, that will be challenging for her heart?
