This is what I was frantically asking myself at 6:30am yesterday. Thank you Google and this person who encountered the same problem. I thought that Jeffrey was going to die when he started foaming at the mouth. Imagine waking up, it’s dark, your black cat is freaking out and running around your room, neon green shit is being spattered all over the place in his trail. It was somewhat traumatizing. Luckily my dear little Jeffrey is okay.
