Well, I tried the Thundershirt on Roxi last night, but ended up taking it off. Roxi is only 3 lbs and even though I bought the smallest Thundershirt they had, it's still a little too big around the neck area. She looked so uncomfortable but she did fall asleep right away. My mom had suggested leaving a light on at night, so I left a small lamp on. And guess what...she got up 2 times but came back to bed with no anxiety at all. I'm going to try it for a couple more nights to see if it continues to help and then I will go out and get a night light for her. Keep your fingers cross for us. Thanks for all the suggestions
