What causes a cat's back leg to limp on and off with no injury?
Cat limping can have a variety of causes, including injury to soft tissues (muscles, tendons, and ligaments), broken bones, patella luxation (slipping kneecap), arthritis, infection, or a back injury. For instance, a partial tear to a ligament may result in intermittent limping, leading a pet parent to believe that the injury is less serious than it is. Arthritis is a common cause of limping, pain and join stiffness in older cats. Arthritic limping may seem worse in the morning and on colder days and usually gets worse over time. Animals of all ages are susceptible to back injuries, which can cause limping and an abnormal gait. Elderly animals are particularly prone to back injuries due to spinal degeneration. Such limps may seem to come and go.
