I don’t allow my cats in my room But yeah they are usually made out of glass beads. But they are amazing. You need one that’s 10% your body weight or something like that. If it’s too light then it doesn’t work as well. I use a 20 pound one which is technically too heavy but I love that it’s so heavy. I have a Gravity weighted sleep mask as well.

I also have compression shirts that feel like a hug and a pressure belt for anxiety during the day. I respond amazingly well to sensory objects.
