Maybe you should follow our laws a little closer. We're losing the battle here in the states. They're putting more and more parrot species on the Endangered Species List because of pressure from the Humane Society of the United States and organizations such as PETA who do nothing for animals other than drum up money with sad commercials to force legislation such as this. They aren't helping endangered species at all, they are making it harder and harder for people to own parrots in captivity and breed parrots in captivity which is a complete and total shame because once they go extinct in the wild, if we don't preserve them in captivity, that's it. Is that what you truly want?
Prime example, the Philippine Red Vented Cockatoo. It was just listed on the ESL and not because our legislature wanted to do it but because HSUS pushed their hand. There are less than 200 of these birds in the wild and yet we have people working very hard in the US to make sure that we at least have them in captivity. They're a very neat and rare species of Cockatoo that isn't well known or well sought after in the pet community, hence not many people even want to own them but conservation efforts are in effect. By placing them on the ESL, the only thing it does is forces people wanting to sell and buy them to either live in the same state or to go through the red tape of having a permit to do so and to be breeders, so it effectively makes breeding them very hard to do and breeders no longer want to bother with it and breeding stock is much harder to come by because crossing state lines becomes harder. It does nothing to protect these birds in the wild at all.
This is how a lot of our laws here work and it's really a sad state of affairs. As for wanting all animals to be against the law to own except for dogs and cats, if you really feel that way, I'm not exactly sure why you own parrots to begin with and I can't help but feel a bit sorry for you. My parrots bring a great deal of love and happiness into my life and I would be incredibly sad if I couldn't keep that in my life. I'd be really sad if future generations couldn't share in that as well.
