Because members of PETA are against anything other allowing animals to roam free and feral. They are as anti-pet ownership as they are anti-fur/leather, etc. ..
Being against pet ownership doesn't make any sense to me at all. I can't be so kind as to think that that PETA has any idea what is good for animals if they're going to claim that pet ownership is wrong. IMO, that's as bad as the HSUS being against dog breeding.
but a hefty fine would be nice, just like they do in the NFL if a player acts up. It would even be nice if a restraining order were to be in place from the judge informing them they are forbidden to attend any events concerning animals.
