I know this says they're for cats but we got it for our Yorkie-Poo. She is already really skittish all the time so when there is a thunderstorm or fireworks (we live near a baseball field where they set them off frequently) she really freaks out.We have tried using calming treats and they do help, but we can only give her one a day and sometimes a storm may go on for hours (or days). We have also tried music, having the tv loud, and even having a white noise machine pretty loud all in an attempt to drown out whatever loud sound is upsetting her.These all help, BUT we have discovered that she is most likely to calm down if we wrap her up in a blanket, cover her ears, and pretty much leave enough of her unwrapped to see and breathe. I should mention that our dog likes to bury her head under things like blankets, pillows, her beds, and if you have her on your lap she will even turn around and bury her head in your armpit lol. So again, while this helped, it wasn't practical or a perfect solution because we can't hold her all the time.I have read somewhere that sometimes covering *just* their ears/head can help them calm down. We already knew that she liked to have her head covered even when there wasn't a loud noise scaring her and it helped to calm her by swaddling her when there was, so we have experimented with just covering her ears/head during a thunderstorm. We would cover her head/ears with a blanket but as soon as we got up and went somewhere she would follow us and the blanket would fall off. Same thing with a scarf. We even tried tying the scarf around her head/neck but it wouldn't stay on her ears and head and would fall down around her neck. So while she looks cute and fashionable it didn't help lol.That's where this comes in.With this, it's basically like a sleeve that you pop their head into. Keep their ears covered (try and fold them down so when you put it on their ears aren't inside out) and keep it on their head just like in the pictures here. It made our dog look hilarious but more importantly, it helped calm her and stayed on her head/ears. She would still follow us around and be right next to us the entire time there was a storm or fireworks but she wasn't actively freaking out. We know this because for her, when she is upset, she will pant heavily and shake. When this was on her the panting stopped and she shook a lot less.So, having said all that, I don't think it is perfect but I do think it is a useful (and funny) tool to help get your cat (or in my case, small dog) to calm down.
