A new ordinance is looking at being passed in Sioux City, IA that limits all animals in a household to three. Typically in the past these types of laws applied solely to dogs and cats, but the city restructured the definition of domestic animals and it applies to almost everything. From the USARK Action Alert:

Sioux City is taking steps to severely limit the number of animals that can be owned by its residents by redefining the term domestic animal (which currently only includes dogs and cats). As redefined, it would include most animals and limit the number per household to no more than three pets in total. This ban narrowly passed its first reading (3-2) so not all Council members approve of this legislative abuse. Local residents must voice their opposition immediately as the next reading and vote are scheduled for Monday, October 10.
...
The only pets excluded from this new ban would be hamsters, guinea pigs, and fish. It would be legal to have 300 hamsters but illegal to have three crested geckos or three lovebirds. Regardless of the species, the numbers assigned to these “pet limits” are completely arbitrary and capricious with no logical or scientific grounds to argue the merit. One person may responsibly and humanely care for seven dogs while another person may not be able to responsibly have one dog. The problem is isolated to the bad owners and not how many pets people have. Punishing responsible animal owners by claiming it will stop irresponsible actions by others is bad government at its finest through collective punishment.
