I've not seen those before. That's neat!
It's mostly been hairball vomits that they've had. Kunkka did throw up once from overeating but that's pretty rare. I have Kunkka and Dazzle on the same food that CJ eats and they've been doing pretty well with it. Just so much dang fur!
And I'm the one out of three in the house that isn't afraid to clean it.
