Expensive to breed carnivorous animals though. Chickens, cows, etc. you can directly raise on cheap vegetable matter.

I used to work in the pet industry and an oft cited statistic was that 1,000,000 cats and dogs are euthanized every year in the US. It would never happen for cultural reasons but, it seems like China could be a booming market for selling these animals as meat instead of letting it all go to waste.

I think veterinary drug residue is a big concern here too

Presumably these cats and dogs would be slaughtered the same way that current plate-bound cats and dogs are slaughtered.

The bigger issue would be how these animals are bred. Are the eaten cats and dogs typically more muscular and fatter than those raised as pets?
