If you own a cat in Illinois and have wondered whether declawing is still a legal option, the short answer is yes — but the legal picture is shifting faster than many pet owners realize. No statewide ban exists as of early 2026, though the procedure faces growing opposition from legislators, veterinary organizations, and at least one Illinois municipality that has already outlawed it.
Understanding where Illinois stands right now, what proposed legislation would change, and which local ordinances may already apply to you can save you from an unexpected legal problem. This guide walks through each layer of the law so you can make an informed decision for your cat and your household.
Is Declawing Cats Legal in Illinois?
No Illinois state law prohibits veterinarians from performing elective declawing on cats. A veterinarian licensed in Illinois can legally offer the procedure, and a cat owner can legally request it. That said, the legal landscape is not as settled as it once was.
Senate Bill 257, introduced in January 2025, would create a new Cat Declawing Act prohibiting the procedure statewide except when medically necessary. The bill remains in the early stages of the legislative process. This is not the first attempt to pass such a law in Illinois.
House Bill 1533, introduced in 2023 by Representative Barbara Hernández, passed the Illinois House on a 67–38 vote in March 2023. It never received a Senate vote and died when the 103rd General Assembly session ended in January 2025. SB 257 is the successor effort, carrying forward the same core prohibition into the current legislative session.
Important Note: Because SB 257 has not been signed into law as of June 2026, the information in this article reflects current Illinois state law. Monitor the Illinois General Assembly bill status page for updates on SB 257’s progress.
Illinois cat owners should also know that the American Veterinary Medical Association (AVMA) has a stance against declawing as an elective procedure, advocating for client education on alternatives and recommending against declawing unless medically necessary. Many veterinarians in Illinois also refuse to perform the procedure due to ethical concerns, even if it is legal in their area. So even where the law permits it, finding a willing provider may be harder than it used to be.

What the Law Actually Bans in Illinois
Because no statewide ban is currently in effect, there is no active prohibition for most Illinois residents to navigate. However, understanding exactly what SB 257 proposes to ban is important — both because it may become law and because Evanston’s existing ordinance uses nearly identical language.
SB 257 provides that a person may not request or perform surgical claw removal, declawing, or a tendonectomy on any cat or otherwise alter a cat’s toes, claws, or paws to prevent or impair the normal function of the cat’s toes, claws, or paws. Notice that the bill targets both the person performing the procedure and the person requesting it — meaning a cat owner who seeks out an illegal declaw could face penalties, not just the veterinarian.
Under SB 257, “declawing” means an onychectomy or any other surgery that amputates or modifies part of a cat’s paw to remove the claws. The bill also separately bans tendonectomy, a procedure where the tendons controlling the claws are cut so the cat can no longer extend or use them normally.
Beyond those named procedures, the bill includes a catch-all: any procedure that alters a cat’s toes, claws, or paws in a way that prevents or impairs their normal function would be prohibited. This broad language is designed to prevent workarounds that achieve the same outcome through a different surgical method.
Key Insight: The Downers Grove ordinance — which took effect January 1, 2026 — clarifies that “declawing” does not include the trimming of nonviable claw husk or placing nonpermanent nail caps. Routine nail trims and soft nail caps remain fully legal everywhere in Illinois.
Declawing is an invasive surgical procedure in which the last bone of each of a cat’s toes is amputated — similar to severing a human finger at the last knuckle. It is commonly performed for human convenience rather than for the cat’s well-being. This characterization from the Animal Legal Defense Fund is reflected in the legislative findings behind both the proposed state law and the local ordinances already in place.
Therapeutic Exceptions to the Declawing Ban in Illinois
Every piece of Illinois declawing legislation — past and present — carves out a narrow medical exception. This exception is not a loophole for elective procedures; it applies only when a cat’s health genuinely requires surgical intervention on the claw.
SB 257 authorizes a veterinarian, for a medically necessary and therapeutic purpose, to perform surgical claw removal, declawing, or tendonectomy on a cat or otherwise alter a cat’s toes, claws, or paws. The key phrase is “medically necessary and therapeutic” — convenience, behavior management, or furniture protection do not qualify.
If enacted, this legislation would protect countless cats in Illinois from being subjected to a painful and unnecessary surgical procedure while still allowing declawing in the rare cases when it is necessary for the health of the cat, such as in the treatment of cancer of the nail bed. Other recognized therapeutic scenarios include severe, untreatable infections of the nail bed and tumors that cannot be addressed any other way.
A key distinction lies in whether declawing is performed for medical reasons or as an elective procedure. Medical necessity typically involves situations where declawing is the only option to alleviate a medical condition affecting the cat’s claws, such as untreatable infections or tumors.
One argument sometimes raised in legislative debates is that immunocompromised owners need their cats declawed for safety. The evidence does not support this position. The NIH, CDC, US Public Health Service, the Infectious Diseases Society of America, and the Canadian Medical Association have all specifically stated that declawing is “not advised,” even for the animals of persons who are severely immunocompromised, including those with HIV. If you have health concerns related to cat scratches, speak with your physician about safe handling practices rather than pursuing surgical options for your cat.
City and County-Level Declawing Restrictions in Illinois
Even without a statewide ban, some Illinois residents are already subject to local ordinances that prohibit elective declawing. If you live in one of the municipalities below, you need to know the rules that apply to you specifically.
Evanston: Illinois’s First Municipal Ban
In December 2024, Evanston became the first Illinois city to ban cat declawing by ordinance. Evanston’s law mirrors the proposed state legislation: it defines the prohibited procedures, allows exceptions for therapeutic purposes, and imposes a $2,000 fine for violations. If you live in Evanston, elective declawing is already illegal for you right now — not just a possibility down the road.
Downers Grove: A January 2026 Effective Date
Downers Grove passed its own cat declawing ordinance in early 2025. Based on Village Council direction, the ordinance was amended to reflect a January 1, 2026 effective date, and language was added providing for an automatic repeal of the ordinance if the State adopts a similar state law. This means the Downers Grove ban is currently active as of this writing.
The ordinance defines its terms precisely. Onychectomy is defined as a procedure in which a portion of the paw of a cat is amputated to remove or disable a claw, including procedures commonly referred to as declawing. Tendonectomy is defined as a procedure in which the tendons to a cat’s limbs, paws, or toes are cut or modified so that the normal functioning of the claws is impaired.
Buffalo Grove: A Softer Stance
Buffalo Grove took a softer step in August 2024, issuing a proclamation supporting state-level action and urging local veterinarians to stop performing the procedure voluntarily. This is not a binding ordinance — no fine or legal penalty applies in Buffalo Grove — but it signals the direction the community is moving.
No other Illinois municipality had taken formal action as of early 2025. However, given the pace of local legislative activity, that number could grow. Before scheduling any procedure, check the current ordinances in your specific city or village.

Penalties for Illegal Declawing in Illinois
Because there is no statewide ban yet, state-level penalties do not currently apply. The penalty framework discussed here reflects what SB 257 would impose if enacted, plus the fines already in force under Evanston’s and Downers Grove’s local ordinances.
Proposed State Penalties Under SB 257
SB 257 would impose civil penalties for violations of the ban, which would increase with subsequent violations. The earlier House Bill 1533 used a tiered structure as a reference point for what the final state law might look like. That legislation prescribed penalties of $500 for a first offense, $1,000 for a second violation, and $2,500 for a third or subsequent violation.
SB 257 also authorizes the Attorney General and State’s Attorneys to seek civil penalties against those seeking to have declawing procedures performed and injunctions against veterinarians performing the procedure. This dual enforcement mechanism — targeting both the client and the provider — is broader than what many pet owners might expect.
Current Local Fines
In Evanston, the fine for performing an illegal declaw is $2,000 per violation. In Downers Grove, the ordinance uses a similar escalating structure. The fine reaches $2,500 for a third or subsequent violation, and each declawing procedure constitutes a separate and distinct offense to which a separate fine applies. That means a veterinarian who performs multiple illegal procedures in a single session could face compounding fines.
Pro Tip: Even in areas of Illinois where elective declawing remains technically legal at the state level, you may still face civil liability or professional consequences. Veterinarians risk license complaints filed with the Illinois Department of Financial and Professional Regulation under the Veterinary Medicine and Surgery Practice Act of 2004 if a procedure is deemed to violate professional ethical standards.

Alternatives to Declawing in Illinois
Whether you are in a municipality that has already banned elective declawing or simply want to avoid a procedure that carries real surgical risks, several effective alternatives exist. Possible complications of declawing a cat include infections, behavioral changes, chronic pain, and nerve damage. The options below address scratching behavior without any of those risks.
Regular Nail Trimming
Regular nail trims can significantly reduce damage from scratching and are a simple alternative to declawing a cat. When nails stay short and blunt, they are less likely to snag on fabric or cause injury. Most cats benefit from a nail trim every two to four weeks. Use a pair of cat-specific nail clippers and gently press on the paw to extend the claws. Trim just the tip, avoiding the quick, which is the pink part of the nail containing blood vessels.
Soft Nail Caps
Soft nail caps offer a reliable alternative to declawing a cat. These small, flexible covers fit over each claw and prevent damage without affecting your cat’s ability to retract their nails. The caps are typically applied with a safe adhesive and fall off naturally after a few weeks. They are available in various sizes and colors. Soft nail caps work best for indoor cats and can be reapplied every four to six weeks.
Soft Paws should not be used on cats that go outside, since nail caps will blunt the claws and also impede a cat’s defenses. If your cat spends time outdoors, regular trimming is a better fit.
Scratching Posts and Environmental Enrichment
Provide your cat with suitable scratchers where they can exhibit normal scratching behavior. Scratchers come in multiple styles and textures. It is important to experiment with a variety of textures and types of scratchers to determine which your cat prefers. Some examples include scratching posts or pads with sisal rope or rough fabric, cardboard boxes, and lumber or logs.
The placement of scratchers is very important. Cats often stretch or scratch when they wake up, so consider placing one near where your cat sleeps. It may also be effective to place a scratcher near or in front of a cat’s preferred, yet undesirable, scratching object.
Positive Reinforcement Training
Training your cat to scratch appropriate surfaces is an effective alternative to declawing. Cats are intelligent animals and can learn to follow commands with the right approach. Positive reinforcement is key. Reward your cat with treats, praise, or playtime whenever they use their scratching post.
In addition to positive reinforcement, you can use deterrents to discourage inappropriate scratching. Double-sided tape, aluminum foil, or commercial deterrent sprays can be placed on furniture to make it less appealing to your cat.
Pheromone Products
Consider using synthetic facial pheromone sprays and/or diffusers to help relieve anxiety or stress. Apply a synthetic pheromone spray such as Feliway on the objects or areas in your home where your cat has exhibited undesired scratching. Do so after cleaning with soap and water to remove the communication marking scents left by your cat’s paws. Applying daily comforting pheromones can prevent your cat’s need to mark these areas again.
For persistent problems, a consultation with a certified animal behaviorist can identify triggers and develop a training plan. These consultations typically run a few hundred dollars, which compares favorably to the cost of surgery and the recovery period that follows it.
Illinois cat owners have more resources and legal context to navigate than ever before. The state has not yet banned declawing, but Evanston and Downers Grove have, pending legislation could extend that prohibition statewide, and a growing number of veterinarians are declining to perform the procedure regardless of what the law requires. Staying informed about your local ordinances — and exploring the humane alternatives above — puts you in the best position to care for your cat responsibly.
