So about the Ohio pet eating, the first thing that made me ❌ Doubt is that we (folks in western civilization) eaten cats before, and they are desperation food world wide. Captured cats turned into food was called roof rabbit during the London blitz. There's little meat to bone, and reports say it's extremely gamey. Even scavengers will pass on kittens if they're not desperate.
There are some Asian cultures that eat dog, which is a regional food in some parts of China, what is a product of living in a region where wild dogs (such as dholes) dwell and prey on children and wildlife. But this isn't a food of choice, nor one for which they'll hunt pets unless they're desperate (in which case, some blame has to fall on social services for letting people go hungry), and there are markets for dog that has been specifically bred to be eaten, which is different from fancy dog breeds we are used to.
The local wildlife such as Florida's alligators, or California's coyote population (coyotes lurk everywhere across the US) are often that desperate and will totally eat your pets or livestock, so if Mr. Bitey goes missing, that's your culprit in the rurals. In the meantime law enforcement in the United States will indiscriminately kill dogs, with officers afraid of even chihuahuas and toy terriers. The police kill rate for dogs averages around 50,000 dead pooches a year.
