Gwen D’Amore –
With 2 cats, who sometimes are stressed, with boarding or restricted access to all areas of home, I have tried the two more popular and advertised products for stress. By far, the TopSum product worked the best. My Tortie cat who is independent and resistant to petting, has now started “allowing” us to touch and pet her. I am pleased with this product and would recommend it.
