Why are reliable animals unfair to enjoy as pets within California?

I was looking through good pets to get, and since contained by California I've noticed a few that aren't allowed here when they are in the majority of states. Sugar gliders, hedgehogs, ferrets...can somebody dispense me a list of all the animals that are illegal surrounded by California but legal in other states and a reason why?

I consider the most important reason is that these animals - if they escape and breed contained by the wild - they will displace native populations of animals, birds, squirrels, etc.

There are too many tale of non-natives species taking over the habitat of native animals. Hedgehogs (egg eaters) have decimated plentiful bird species in the English Channel Islands. The Cane Toad in Florida is poisonous to pets (dogs) and is pushing out local fish/frog species. etc. Then those native animals may actually go extinct because they can not compete successfully. So - some animals are disallowed for a very good reason!!

Answers:    There are a great deal of animals that are not allowed in California because of the following reasons:
1. Rare or dying out in California
2. Will kill off other populations
3. Will not thrive here
4. Are not undisruptive.
