Is this scale or mealybug, and what should I do?

[Grim Tuesday]

Saw this little asshole munching on my plant this morning. What is it and how can I get rid of it, and beyond quarantining the plant, to make sure it doesn't invade the rest of my collection? I currently have neem oil, rubbing alcohol and insecticidal soap from a previous infection of spider mites. I am usually against heavy hitter insecticides but these pests are driving me nuts. Is there anything that would be safe for indoor use around cats?

Here is a picture of the invader:
