One point, one question, and one opinion.
Point-Cat breeding is not seasonal, they go for any time the female is in heat, which can be any time of the year.
Question- Would the nutritional value be the same cat to rodent I wonder?
Opinion- It comes done to a matter of honesty (read in here "honor") If you bought it as a pet and then used as food, not very honest.
I personally think that if cats and dogs are a good food source for snakes than why not, it's better than just 'putting them down' and filling up the land fills with dead bodies.
