Mason was charged with PC 597 b according to the dept. press release. He was basically charged with not providing food, drink or shelter for his animals. He has to provide "ordinary care." He was providing this and a lot more. They had food, water, shelter, vet care. Not all were neutered but that's not mandatory.
597 b is a wobbler, you can charge as misdemeanor or felony. The dept wants to go for felony because it makes their ACTF stats look good.
Obviously, if Mason has a ton of vet bills, had most "fixed," and they looked well fed, as did Muffin and "Sonny" held by Det. Orgetga, then he is not guilty of a PC 507b violation, and definitely not as a felony.
