u/ButterfliesandSkulls

This is Boef, he's 9 weeks old and I've had him for a week 1/2. He's normally very curious and extremely active. But every day it seems a switch goes off, and he will run around the cage like crazy for a few seconds, and then he will lie frozen for a hour or longer🙁 It happens out of the blue, I don't think something scares him? He also doesn't grow a lot.. He's with a friend in a seperate cage from the rest of my boys, maybe thats stressful? I worry it might be something wrong in his head..

Has anyone experienced this before? The vet wasn't very helpful🙁
