[quote=“Bu Lai En”]I don’t see why killing other animals is any better than killing dogs or cats, but a law stopping the klling of, say, just cows, although inconsistent, would at least save the cows.

:bravo: Well said re: inconsistency. I am often confused by the argument “Well if you aren’t going to do Good Thing B, C, and D, then you shouldn’t do Good Thing A either.”
One factor that would be relevant to questions like this, however, is the extent to which one good is seen by consumers as a [color=blue]substitute[/color] for another.
Using your example of cows:
If consumers treat pork or chicken (or dog or cat meat) as a reasonably close substitute for beef, then a law stopping the killing of cows may well result in higher numbers of pigs, chickens or other animals killed. If, on the other hand, most people basically think “Well I really was in the mood for beef, but if I can’t have been than I guess I’ll have the tofu veggie plate” then this would not be an issue. My intuition is that the goods are imperfect substitutes – in other words, if cows were off limits then there would be some substitution of pork or other meat, but not 100% substitution.
Applied to cats and dogs:
If beef, pork etc. is seen as a substitute for dog or cat, then it seems likely that the proposed law would slightly increase the number of cows and pigs killed. However:
(1) I am not arguing that this is a good reason not to enact the proposed legislation, merely that it is one factor that might be considered by people who value the lives of all of these animals equally (which most of us, perhaps, do not).
(2) Even if there is substitution, the magnitude of the effect would appear to be quite small, since the quantity of dog and cat meat eaten is relatively small.
