I have 5 cats and 2 dogs . Within 10 minutes of plugging in this is what my ex Ferrell cat did , please see video in comments.I’ve spent the last 8 months at home due to my health I’ve just started leaving the dogs for the first time and they were trashing the house and pulling up the carpet . Our first week of using the plug in and they have been left for up to 2 hours and no problems, even calm when I return. I think I might be sending the dog cage back I ordered as there is no need for it now . I’m truly amazed.
