Nova Scotia becomes first province to ban declawing of domestic cats
HALIFAX — Nova Scotia has become the first province to ban medically unnecessary cat declawing, part of a worldwide movement against the practice.
The Nova Scotia Veterinary Medical Association decided Tuesday to amend its code of ethics to make the practice of elective and non-therapeutic declawing ethically unacceptable.
It will come into effect on March 15, 2018, following a three-month education period.
Dr. Frank Richardson, registrar of the association, said the decision follows years of discussion by veterinarians, surveys, public input, and a recent statement from the national association.
The Canadian Veterinary Medical Association strengthened its stand against declawing domestic cats in March, saying the practice causes unnecessary and avoidable pain.
Vets’ groups in many other provinces are having active discussions on the issue, Richardson said: “It’s on everybody’s radar.”
Richardson said while declawing was popular 20 years ago, fewer and fewer veterinarians have been willing to perform the procedure.
“The number is getting smaller and smaller each year. I think if we did nothing it would die off on its own,” he said.
Dr. Hugh Chisholm, a retired veterinarian who has been pushing for the change, said while some municipalities have enacted regulations against declawing, Nova Scotia becomes the first province or state in North America to declare the practice unethical.
“It’s a great day. I’m so proud of the Nova Scotia Veterinary Medical Association,” said Chisholm, Atlantic Canada director for the Paw Project.
“You are amputating 10 bones from 10 digits on the paws of a cat, and if that doesn’t constitute mutilation, I don’t know what does,” he said.
The practice has already been banned in the U.K., Europe, Australia and several California cities. New Jersey is considering a law that would ban the practice unless a vet decides the operation is medically necessary.
“Now that we have this success in Nova Scotia, I will be contacting the other provincial veterinary associations to encourage them to do the same thing. I think it’s just a matter of time,” Chisholm said.
For years some pet owners have had their cats declawed to prevent scratches to furniture, people and other pets. But the Canadian Veterinary Medical Association says scratching is normal behaviour that cats use to mark territory, help with balance, climb and defend themselves.
Chisholm said there will still be cases where declawing will be medically necessary.
“Those would be very rare cases, but yes if it is in the cat’s best interest to have a claw removed or a few claws removed because of trauma or infection, then yes it is the right thing to do. To do it because you’re worried your sofa is going to get picked or scratched is just wrong,” Chisholm said.

Dr. Evan Antin hails from Kansas City, Kansas where he grew up spending the majority of his childhood in search of native wildlife including snakes, turtles and insects. He went on to study evolutionary and ecological biology at the University of Colorado at Boulder and spent multiple semesters abroad in Australia and Tanzania to learn more about their respective ecosystems and fauna.
In addition to his love for cats and dogs, Dr. Antin’s passions lie in exotic animal medicine and interacting with exotic animals in their native habitats around the world. For more than a decade Dr. Antin has made an effort to seek opportunities to work with wildlife on a domestic and international level to include locations such as Central America, Australia, New Zealand, South America, Eastern and Southern Africa, South East Asia and a variety of North American ecosystems. The accumulation of Dr. Antin’s hands-on experience with exotic animals has prepared him exceptionally with their handling, husbandry, and enrichment. He is capable of caring for small, delicate animals; large, dangerous animals; and of course our beloved household dogs & cats with ease and confidence.
Dr. Antin has been happily employed as a full time associate at CVVH directly following his graduation from Colorado State’s veterinary school in 2013. Since then he’s developed clinical medical & surgical skills to help provide the right care for the dogs, cats, exotics and wildlife of the Conejo Valley.
Dr. Antin currently lives near Calabasas, California with his dog, Henry, his cat, Willy, his savannah monitor lizard, mangrove snake and an assortment of tropical freshwater fish. Other hobbies of his include traveling, scuba diving, snowboarding, hiking, and weightlifting.
6 yr DLH brought in for possible abscess on front right paw. The owner just noticed lump on paw a couple days ago and was expecting it to be an abscess. After further inspection DVM noticed what looked like nail peeking through a tiny spot under the skin. After sedating and removing the hair, he cut open the “abscess”… This poor cat was declawed over 4 years ago before the current owner received him. When declawing, the previous DVM must have left enough behind on the dewclaw to allow it to grow back. This is at least 4+ years of nail curled around on itself underneath his skin!! Craziest thing I’ve ever seen!

Commentary: It’s time for veterinarians to stop multilating cats’ feet
Declawing is a barbaric procedure that violates bioethical principles and sets feline patients on a path to chronic maladaptive pain.
I applaud the American Association of Feline Practitioners and the fact that it has (finally) taken an appropriate stand against the mutilation of cats through toe amputation. I am saddened that any compassionate veterinarian would object. It is worth remembering that we are one of the only developed nations on the earth that still allows it.
Amputating the last phalanx (P3) of the toes of cats was once considered a “commodity” procedure, commonly performed by well-intentioned veterinarians. As time has passed and our understanding of feline pain, biomechanics and quality of life has evolved, we now recognize many downsides to this procedure and truly no upside.
For the purpose of this commentary, let’s consider three distinct perspectives on the issue of feline toe amputation:
The clinical bioethical perspective
The pain perspective
The biomechanics perspective.
Clinical bioethical perspective
Cats are sentient beings with moral agency who, it has been recently argued, should be approached with the same consideration as nonverbal children.1-5 It behooves us to consider them within the context of the foundational principles of clinical bioethics.
The four cornerstone principles of clinical bioethics have been described as respect for autonomy, nonmaleficence, beneficence and justice.6 Let’s look at each of these in turn as we examine the clinical bioethics of feline toe amputation.
Respect for autonomy means we must consider cats’ preferences. If cats could be given a choice between being subjected to multiple toe amputations and maintaining intact feet, one can easily make the case that cats would prefer intact toes and feet, avoiding the pain and disfigurement associated with multiple toe amputation.
Nonmaleficence means “do no harm” or “avoid harm.” The question then becomes, does amputating all of a cat’s front toes (P3s) cause harm? Amputation is painful, potentially for the rest of the cat’s life. It also forever alters the way a cat walks, prevents natural (scratching) behavior, and forever prevents the cat from being able to defend itself by fighting or climbing to escape a threat. Clearly toe amputation causes harm.
Beneficence means to act in a being’s best interest. Can we truly argue that amputating all of any cat’s third phalanges of the front toes is ever in that cat’s best interest? It appears that the answer to this question is a self-evident “no.”
Justice is the fourth cornerstone principle of clinical bioethics. Translating this for application in veterinary medicine focuses on fairness. The relevant question to ask is if amputating the third phalanx of each of a cat’s front toes could ever constitute fairness to the cat within the context of its life and lifestyle. Considering all of the compromise that toe amputation creates, as a formally trained clinical bioethicist, I respectfully submit this does not reflect fairness.
Multiple studies have demonstrated that most cats receive woefully inadequate pain prevention and management for procedures like spays and neuters—procedures far less traumatic than multiple toe amputations. The pain literature clearly demonstrates that acute pain poorly managed at the time of the trauma often leads to permanent pain states. This means ongoing, self-sustaining, chronic maladaptive pain that constitutes lifelong torture.7,8
The few studies that have evaluated either the presence of leftover bone fragments or regrowth of sharp bone spurs after toe amputation demonstrate that an embarrassingly large number of cats suffer from this extra bony tissue.9 These sharp shards perpetually poke at the underside of the skin at the end of each toe stump, making every step like walking on needles or nails.
Finally, we know from pain physiology that when we sever a nerve, there is a high risk of creating self-perpetuating neuropathic pain. Humans most commonly develop neuropathic pain as a result of conditions such as amputation, direct nerve trauma, shingles and diabetes. People who develop neuropathic pain can describe how it feels, so we know the unremitting torture they endure each and every day—tingling, burning, electric-like pulsed pain, pins and needles. We also know that once chronic maladaptive neuropathic pain is in place, these people report ongoing challenges relieving pain.10-12
We know from pain and neurology research that companion animals are “wired” precisely as we are. When nerves are cut—as they are in feline toe amputation—the probability that the cat will develop neuropathic pain is exquisitely high. These cats can go on to develop many different aberrant behaviors. These may include:
reluctance to walk on certain surfaces
reluctance to jump onto or off furniture, window ledges and so on
overgrooming of feet or legs.
These cats must walk on their painful feet!
Finally, we must consider how feline toe amputation forever alters the biomechanics of the patient.
When a cat is subjected to toe amputation, in addition to having the last bony phalanx removed, all of the surrounding tendons and ligaments that attach to that bone are severed. This changes the architecture of the feet, thus changing the biomechanics of how the feet work. Because approximately 60 percent of the cat’s body weight is carried on the front feet, altered biomechanics changes the way the entire body moves. If we superimpose chronic maladaptive neuropathic pain in the feet onto altered front foot biomechanics, we amplify the downstream implications of the cat moving in an abnormal fashion. The altered biomechanics can significantly interfere with the cat’s ability to exhibit normal cat behaviors.
We also know that the vast majority of cats 10 years of age and older suffer from degenerative osteoarthritis (OA) in at least one joint.13,14 The majority of cats who develop OA in later life have it occur in their equivalent of the human lower back—where the spine and pelvis come together. When the biomechanics of movement are altered, so are the forces generated throughout the body’s joints—in particular the joints of the spine.
The repetition of ergonomically unsound movements over time creates microtraumas to these joints, which can contribute to the development and progression of OA. Then, OA contributes to ongoing chronic maladaptive pain in these cats. As both a board-certified specialist in rehabilitation and a pain expert, I find this completely preventable, endless cycle of altered biomechanics and chronic maladaptive pain to be a call to action.
The bottom line is that amputating the last phalanx of the toes of cats violates those cats on many levels—bioethically; from an acute pain perspective; from a neuropathic pain perspective; from a biomechanical, movement and lifestyle perspective; and from an OA and chronic maladaptive pain perspective. It is time for this arcane and barbaric mutilation procedure to be removed from the veterinary surgical lexicon.
