Did you read the article? Because if you did, instead of rushing to bash my post, you'd see that it mentions things like Goldfish. It also specifically refutes the point your posts makes in the second paragraph. So your point is that keeping goldfish in a tank for the first year of their life is so inhumane and instead, I should buy goldfish from my neighbor and put them in a tank instead?
You are thinking of this from the perspective of a poor little puppy from a puppy mill stuck in a shop window. I agree, that's a terrible thing, and that's what the original (which was still absurd) was meant to prevent. However, this law has been expanded to include pretty much all animals. It's so absurd and so ridiculous that I can't believe people (you?) would take this seriously.
What it boils down to is we have people who are butt-hurt that the majority of Americans don't care about the feelings of a fish or the feelings of the rat they are going to feed to their python. So these people are trying to push their worldview on everyone else - regardless of the fact that "treating animals like commodities" is something that humans have been doing since the first creature was domesticated.
So yeah, I do get your point, I did read the article, and I think you are dead wrong. These people are off-their-rocker PETA wackos that don't want anyone to own any pets, ever. In fact, other sources go on to say that "eventually, there would likely be no more tropical fish or other exotic pets in San Francisco (except those imported illegally). Purebred dogs and cats might become a thing of the past as well."
