because he's finding himself in need of a whole lot of dental work, and is in a position where he's needing a bit of help with some of the finances (he's worked out a payment plan for a lot of it).
He's posted about it here on Inkbunny and on Furaffinity so please look there for more details! I've already sent some money myself, but even if you can't manage anything right now, your own signal boosts would be appreciated!
