Have any of your cats tails gone limp? My cat usually walks around with her tail way up in the air but the past couple of days I've noticed the two three inches from her bottom will be erect while the rest of her tail is fallen slumped over just dangling there. She is an indoor cat and there is no injury (that we know of). Can't feel any bumps and she doesn't seem to mind me touching it. Has this happened to anyone elses cat?
