There may be the following reasons for a cat’s leg suddenly limping without trauma: firstly, the cat may have a strained muscle, which will cause pain when it moves and appears to be limping. In addition to this, a fracture can also appear as a walking limp. A fracture also has no obvious trauma but can cause severe pain, and some feet may appear swollen when fractured. It may also be dislocated and a hospital visit is recommended for a radiograph.
