I can't remember where I read it but Geranium oil and Pine needle oil are safe for cats to use.
Recipe:
5 drops Geranium oil
5 drops Pine needle oil
1 teaspoon MCT coconut oil
Apply a few drops with an eyedropper to your cat's nose bridge and the sides of the nose bridge over the sinus plex. She stopped sneezing in a few hours. The next day only a few times so re-apply once daily til they stop sneezing altogether.
