They know that if they went after dogs and cats, they would be out of a job.I totally agree. Just keep a mix of live bearers if the situation becomes too bad. I own budgies myself and even if I'm not in the USA I worry because say if one of my budgies die, the other would suffer because these are social birds. What makes cats and dogs so special?
Make no mistake, they will eventually come for them too one their noose of control tightens, claiming Global Warming or some other lame excuse.
