Pets Trespassing & At Large
It is illegal for an owner to allow any animal to trespass on the private property of another. It is also illegal for any person to allow pets, other than cats, to be at large on public property.
(Cats are allowed to be at large on public property, but not trespass on private property.)
“At Large” Means
- that the animal is not physically restrained on the owner’s (or keeper's) premises (or vehicle)
- or that the animal is not physically restrained while on public property by a leash, tether or other physical control device and under physical control of a capable person. The leash or restraint device must be 8 feet in length or less.

Steps for Solving
- If you know who owns the animal, talk to them to let him or her know about the problem. He or she may be willing and able to solve the issue. If the animal is a cat, see "Keeping Cats Out of Gardens".
- If the owner is unwilling to retrieve his/her animal (or keep it restrained) or you don’t know who owns the animal, you have several options:
- Bring the animal to MCAS during open hours
- You may be able to call MCAS and arrange to have the animal picked up by an animal control officer
- You may file a formal complaint using either the Animal Nuisance Complaint Form
(PDF, 166KB) or the Cat Trespass Complaint Form
(PDF, 170KB). Both forms must either be signed by at least two other neighbors (three people total) or if signed by one person, it must be accompanied by photos and/or video showing the violation. After you have completed the animal nuisance complaint form, you can either bring it to
or you may mail it to:
- If an animal is at large because it is a stray, visit our found pet center.
