Jax Chinchilla Rescue
Kingston has done that, just falls over and lies there for no reason v_v
What he does the most is just freeze, I can poke at him and pick him up and he's awake but wont budge, then after a bit he'll wake up and be all normal again wondering why I'm touching him. Its weird.
Just an FYI, my chin Chula literally sleeps with his eyes open. I have never seen his eyes closed.
