​Hardened resin-like small pieces found in bed

I keep finding these hardened resin-like pieces in my bed randomly. I feel like the size varies every time I find one. I do have an indoor cat, and I originally thought it might be an extremely weird ball of his ear wax, but it’s just so strange. I highly doubt it has anything to do with bugs, but I suspect it might have something to do with my cat since it’s only started while I’ve had him. However, I’ve had him a year & this has been happening for a couple months. Pls help I’m so concerned
