Passed by Senate on January 18, 2024. Passed the House on December 31, 2024. Signed into law January 8, 2025. Took effect April 8, 2025. Read the text of the law.
It is now illegal to declaw a cat in Massachusetts, unless medically necessary. Governor Maura Healey signed this important bill into law in January 2025. Thank you to sponsor, Senator Mark Montigny, and Joint Committee Chairs State Representative Tackey Chan and Senator John J. Cronin for your support and determination. We also want to thank Senate President Karen E. Spilka, Speaker Ron Mariano, Senate Ways and Means Chair Senator Michael Rodrigues, and House Ways and Means Chair Aaron Michlewitz for your leadership this session. The House and Senate both showed that animals, wild and domestic, are important to Massachusetts.
This law prohibits the declawing, onychectomy, dactylectomy, or phalangectomy of a cat. Declawing involves the removal of the claw and the first bone of the toe. The operation is usually performed on the front feet, and is in fact an amputation comparable to the removal of all ten human fingertips at the first knuckle.
A cat’s remarkable grace, agility, and sense of balance are due in part to its retractable claws, which allow the cat to establish footing for walking, running, springing, climbing, and stretching. A cat’s claws are also its best defense mechanism—a declawed cat let outside would have no way to defend themself if need be.
The outer part of a cat’s claws regularly become frayed. When cats scratch, they pull off this outer part and expose sharp, smooth claws. Scratching is also a way of fulfilling a strong instinctive need to mark territory. Not only do cats mark objects by visibly scratching them, but the scratching deposits secretions from glands in the feet that can be smelled by other cats. Scratching can also provide valuable stretching and foot-muscle exercise.
The standard declawing procedure calls for the removal of the claw and the first bone of the toe. The operation is usually performed on the front feet, and is actually an amputation comparable to the removal of all ten of the human fingertips at the first knuckle. The cat often experiences pain in the recovery and healing process and sometimes experiences persistent pain.
Medical risks
An incorrectly positioned cut during declawing surgery can remove too much of the toe, taking with it part or all of the toe’s pad. But if the whole claw is not removed, misshapen claws can grow back. In addition, if a bone fragment is left at the surgery site, it may become a source of infection. Both claw re-growth and infection necessitate additional surgery. Post-surgical blood loss is another concern, but great care must be taken that bandages are wrapped tightly enough to control the bleeding but do not cut off circulation.
Safety risks
A declawed cat must never be allowed outdoors, as the cat’s ability to defend itself or escape from danger has been seriously impaired.
Behavior risks
During the post-surgical recovery process, a declawed cat could find it painful to walk on litter, leading to the development of a life-long aversion to using the litter box.
