We had 4 dead/dying trees taken out of our yard this morning -- well, 3 were dead, and 1 was starting to lean over the roof. I used Jackson Galaxy's (he of 'My Cat From Hell' fame) Spirit Essences on Stella to keep her from freaking out from the noise of chain saws and falling trees. (

Instead of hiding for 24 hours, as she used to do when we had repairmen, etc., she was out ready to eat when I got home! That's a huge improvement. She's still searching the house room by room, but is much less stressed. I originally bought the stuff to mist the carrier before the annual vet visit. I hope it will stop/lessen the non-stop yowling. Sammie has her visit this month - I'll report back if it works. Last year she howled non-stop for the entire visit.
