BOSTON (WBSM) — Thanks to the years-long effort of New Bedford State Senator Mark Montigny, it is now illegal in Massachusetts to declaw a cat.

The legislation, first introduced by Montigny in 2019, was signed into law by Governor Maura Healey on Thursday.

The law prohibits declawing and tendonectomy, unless it is a medical necessity.

“Declawing a cat involves amputating the last bone of each toe, which if performed on a human would be equivalent to cutting off each finger at the last knuckle,” Montigny’s office said in a release.

Montigny himself called declawing “abhorrent.”

“Declawing is an abhorrent practice that most veterinarians view as inhumane,” he said. “But it is also a procedure that is widely misunderstood and requested by owners. This law ensures that veterinarians will no longer have to weigh the choice of providing the procedure, knowing that if they don’t, an owner is likely to just look for someone who will.”

Declawed cats suffer from both acute and chronic pain as a result of the procedure, and it can lead to behavioral side effects like biting and going to the bathroom outside of the litter box.

“Declawing of cats does not improve the human-animal bond and often results in serious medical and behavioral problems,” Allison Blanck, Director of Advocacy at the Animal Rescue League of Boston, said in the release. “Banning this cruel practice, which is in essence amputation, will prevent animals in Massachusetts from needless pain and suffering.”

Montigny has long championed efforts to protect animals, including laws that have restricted dog tethering, prohibited leaving dogs outside during extreme weather conditions, and allowing for breaking into vehicles to rescue animals locked in cars.

He’s also fought for stricter penalties for animal cruelty and abuse.

“As a state we have done far too little to punish heartless abusers and to push back against a weak court system that has too often failed to hold them accountable,” Montigny said. “There are too many people who have committed horrendous abuses to animals that have been unpunished and are walking free to continue to do harm.”

Montigny was recently named Dean of the Senate as the longest-tenured member of the chamber, having served since 1993.

LOOK: Here are the pets banned in each state

Because the regulation of exotic animals is left to states, some organizations, including The Humane Society of the United States, advocate for federal, standardized legislation that would ban owning large cats, bears, primates, and large poisonous snakes as pets.

Massachusetts Wildlife You Can Legally Take Home as Pets

Massachusetts has such diverse wildlife, but also strict limitations on what you can bring home and cuddle. In fact, there are only certain reptiles and amphibians you can keep as pets (so no raccoons, squirrels, bunnies, etc.) and you are only allowed two of each. The state also says "you cannot sell, barter, or exchange them." Also, keep in mind, these are wildlife, so it's probably best to just leave them be and maybe visit a reptile shop instead to get your next pet.
