Summary
Unlike dogs, cats in Mountain View are never required to carry a city license: City Code Sec. 5.53(b) makes cat licensing purely voluntary, letting an owner register a cat if they choose. Cats remain subject to the same running-at-large and public-nuisance rules that apply to other animals, and a voluntarily licensed cat still gets a metal tag or microchip record.
(a)No person shall maintain or board any dog four (4) months of age or older that has not been licensed pursuant to the provisions of this chapter, except:(1)A license shall not be required for dogs owned or under the control of a nonresident of the city that is to be kept in the city for less than thirty (30) days in any twelve-month period.(2)A license shall not be required for dogs temporarily brought into the city for entry into an event, show or exhibition scheduled not more than ten (10) days thereafter.(b)A license shall not be required for cats, but an owner may voluntarily license or register a cat.

Full Breakdown
Sec. 53 draws a sharp line between dogs and cats: subsection (a) makes licensing mandatory for any dog four months or older, with narrow exceptions for nonresidents' dogs kept fewer than 30 days in a 12-month period and dogs brought in for a show or exhibition lasting no more than 10 days, while subsection (b) states flatly that a license shall not be required for cats, leaving registration entirely up to the owner. An owner who voluntarily licenses a cat still goes through the same process as a dog owner: Sec.
54 sets the fee by council resolution, with reduced rates for spayed or neutered animals and a waiver for one altered pet per household headed by a Medi-Cal-qualifying owner over 65; Sec. 55 has the administrator issue the license itself, describing the animal and recording its tag or microchip number; and Sec. 56 lets a registered passive integrated transponder substitute for the metal tag on a licensed cat. Even without mandatory licensing, cats are not exempt from the chapter's general animal rules: Sec. 2 bars any animal, including a cat, from running at large on public or common-area private property without the property owner's consent, and Sec.
11 treats a cat that defecates on a neighbor's yard, sprays offensive odors, or otherwise interferes with a neighbor's enjoyment of their property as a public nuisance subject to seizure.
Violations & Fines
Because cat licensing is voluntary, failing to license a cat carries no penalty, but a cat that runs at large in violation of Sec. 5.2 or becomes a public nuisance under Sec. 5.11 can still be seized and impounded by an animal control officer. Underlying nuisance or at-large violations are penalized under the citywide schedule in Sec. 1.7: up to $100 for a first infraction, $200 for a second within a year, and $500 for a third, with a fourth chargeable as a misdemeanor.
