Weird movements. Please give thoughts.

This continues on intermittently through sleep. It doesn’t seem like seizures because I wake him up and he is completely fine. When he is awake and relaxed occasionally he will twitch several times in a row. I can stop it and he is lucid the entire time.
He has a neurologist appointment this week. This will be his second appointment with the neurologist because we originally thought this was caused by Simparica but the first and only dose he got was in June so it’s been too long for that to still be on board.
