Also known as fractures, most broken bones in cats are caused by trauma, such as being hit by a car or a fall from a height (such as a balcony or tree), Other causes of broken bones in the leg include bone infection, cancer and hormonal imbalances which weaken the bone.

The most common bone breakages seen in cats is a broken pelvis, broken legs, and broken tail. This article refers to broken legs, for more information on broken pelvis in cats, read here.

How can I tell if my cat has a broken leg?

Symptoms of a broken leg may vary depending on the severity. Common signs include:

  • Reluctance to bear weight on the affected leg
  • Limping
  • Pain and tenderness
  • Swelling
  • You may see the bone sticking through the skin
  • Deformity or unusual bend in the limb
  • Rapid breathing if the injury has just occurred
  • Shock

Fractures fall into two categories. Closed and open. A closed (simple) fracture is when the bone remains inside the tissue. An open (or compound) fracture is when the bone sticks through the skin. Open fractures pose a significant risk of infection.

Immediate first aid:

Seek immediate veterinary attention if you suspect your cat has a broken leg. If the veterinarian is some distance away, you will need to immobilise the limb to prevent further injury occurring.

  • Wrap a piece of cardboard, rolled up newspaper or the centre of a paper towel roll around the limb to make a makeshift splint. Wrap the splint in gauze or tape to secure. Make sure the tape/gauze isn’t too tight that it cuts off the circulation. The splint should be long enough to reach the joints above and below the break. When splinting, do not attempt to straighten the leg yourself.
  • If a compound fracture has occurred, place a piece of sterile gauze or a sanitary towel immediately over the wound and then splint. Do not try to push the bone back under the skin.
  • Wrap the cat in a towel and place him on a rigid surface to transport to the veterinarian.

Be aware that a cat in pain may lash out. If you cannot safely splint the leg, transport the cat to the veterinarian. Do not attempt to treat a cat who is resisting as it can cause more harm than good.


Cats with fractures will need to be carefully examined by your veterinarian as they may have other injuries such as a broken pelvis, organs, and soft tissue damage (to name a few).

Your veterinarian will perform an x-ray to check for breakage and assess the extent of the damage.

Treatment depends on the nature of the fracture and will require internal or external fixation to stabilise the bone.

External fixation: 

This method can treat minor breaks.

  • A splint, cast or padded bandage is placed around the leg to immobilise it while it heals.
  • External pins and wires are inserted into the bone vertically to support the bone.

Internal fixation: 

  • Surgery to realign the bones and place screws, pins and, rods into the bone to hold the pieces together while it heals.

In some cases, it may be necessary to amputate the leg.

Home care:

Confine the cat to a small area during recovery and do not let him climb or jump. A quiet room or if necessary, a crate with a bed, litter tray, and food/water bowls.

If your cat has a bandage on the leg, keep it as clean and dry as possible.

Watch for signs of infection such as pain, swelling and an unpleasant odour.

Follow up xrays will be necessary to ensure the bone is healing.

Frequently asked questions: 

Will a cat’s broken leg heal on its own?

This depends on the kind of break, but in general, treatment is necessary to move the broken pieces of bone together and stabilise them to prevent them moving out of place. Infection is also a risk for fractures which are left untreated. Broken bones are incredibly painful and require analgesics to relieve suffering.

How long does it take for a broken leg to heal?

This depends on the severity of the break and the age of the cat. Kittens and young cats heal faster than adults. In general, a soft callus should form within the first 1-2 weeks which will be replaced with a hard callus over the following weeks. The entire process takes between 6-8 weeks weeks.


  1. Hi my name is Sidney I accidentally crushed my kitten foot on chair and it was limping but now looks fine to walk and he was running around playing could he have a broken leg.

    • Hi Sidney, impossible to say without a veterinary check up and xrays. The fact the kitten is now walking fine and playing is positive. Personally, if it was me, and the cat was no longer limping and there were no other symptoms (swelling, pain etc), I’d just wait and see. Good luck.

  2. Hi, my cat fractured his fibula at the end of November. Since it was non-surgical, treatment was just to restrict his movement for 6 weeks. I’ve kept him confined to a dog crate and/or small room but he’s still limping after 7 weeks. Is it normal for there to still be a limp? How long is the healing time? He’s a very active little guy and is not happy about the confinement.
