Do you use the Rescue Remedy for pets or the regular formula?I have used Bach's Rescue Remedy, a homeopathic calming aid made of flower essence. My vet suggested it and it did seem to help. I would rub a drop on the inside of Maggie's ear or give it by mouth. It can be hard to find - look for it at either health food stores or on Amazon.
I use Rescue Remedy for pets or for kids. The regular rescue Remedy has alcohol in it. The kids formula is exactly the same as the pets version and usually $1 or so cheaper. I squirt it right in the cats mouth, but you can put it on a treat, in their water or their food. It works great--I take it myself!
