Summary
Plymouth does not require spaying or neutering pets generally, but City Code Section 915.17, Subdivision 3 makes it mandatory for any cat kept outdoors under the ordinance's veterinarian-documented exemption: an owner whose cat cannot be trained to live indoors, facing euthanasia as the only alternative, must have the cat spayed or neutered to keep it outside legally.
If a cat is unable to be trained to be indoors and the only other option for the cat is euthanasia and the owner produces documentation from a certified veterinarian proving such, the cat may be allowed outdoors. In this circumstance the cat is required to be spayed/neutered, and the owners must agree to be responsible for any damage done to property by the cat and work with the victim and police to ensure solution to any problem being created.
Full Breakdown
The City of Plymouth has no blanket spay-or-neuter mandate for every dog or cat. 17, Subdivision 3 of the City Code, which offers a second, narrower exemption from the general Under Restraint requirement in Subdivision 1. If a cat cannot be trained to stay indoors and the owner's only remaining alternative is euthanasia, the owner may keep the cat outdoors, but only after producing documentation from a certified veterinarian proving that circumstance, and only if the cat is spayed or neutered as a condition of the exemption.
The owner must also agree to be responsible for any property damage the cat causes and to work with any affected neighbor and the police to resolve problems the cat creates. This provision sits alongside the 1998 grandfather exemption in Subdivision 2, which likewise conditions outdoor status on spaying or neutering, but Subdivision 3 remains open to any cat today, not just cats registered by the 1998 deadline. A cat that does not meet either exemption's spay/neuter condition must be kept Under Restraint under Subdivision 1 like any other cat in Plymouth. 05, verify compliance and can impound a cat found outdoors without qualifying for an exemption.
Violations & Fines
A cat kept outdoors without meeting the veterinarian-documentation and spay/neuter conditions of Section 915.17, Subdivision 3, or the 1998 registration conditions of Subdivision 2, is treated as a dog or cat At Large and can be impounded by Plymouth Police animal control officers under Section 915.07. Violating the City Code is a misdemeanor under Section 2000.01, with fines up to $700.00 and up to 90 days in jail.
