I don't think it is fair to levy a tax on all pet owners when exotic pets are the problem. You could try to petition against it if it is a problem. A more practical tax would be exclusively for exotic and wild pets. The law ignores the fact that most pet owners already pay a pet tax in the form of pet rent.
I completely support having a tax on poisonous pets and wild animals. Unless you are raising the animals to harvest venom for anti-venom, trying to save an endangered species, or just giving a home to old retired animals from Hollywood some animals shouldn't be kept as pets. The pet tax should also be applied to animals that aren't native to cover the cost it might cost if they get out and breed.
