Advice on phermone collar

[glittermom]

I would like to give this a try with my cats. I have urinating and some territorial problems. I already use the feliway diffusers. Does anyone have a brand of phermone collar they would recommend?

Since you are already using the pheromone diffusers, I am wondering if something like Jackson Galaxy's Spirit Essences or Australian Bush Flower Essences or Bach's Flower Remedies may not be more helpful?
