There are limits and restrictions for animal ownership even for cats and dogs. A pet owner may keep up to two dogs, or four cats. If you have both cats and dogs, you can have up to two dogs and three cats. You must get a permit for more animals.
Fremont defines an “Exotic Animal” as any poisonous reptile or other wild animal or any vicious or dangerous animal or another animal of wild, vicious or dangerous propensities, requiring a standard of care and control greater than required for customary household pets or domestic farm animals.
