My cat’s hind legs are paralyzed as if broken; is there any hope, can it heal on its own, and if treatable how much would it cost?

Feline hind-leg paralysis is usually caused by spinal injury, motor nerve damage, neuritis, cerebral thrombosis, or poor hind-limb blood circulation; different causes need different treatments and have different costs, and some injuries cannot be cured. Spinal injury is a common cause; if a cat jumps from a height or hits a hard object, the spine may be damaged or compressed, destroying spinal nerve function and causing hind-leg paralysis. In this case, treatment is generally through medication and physical therapy, costing roughly 1000 to 5000 yuan. Whatever the cause, take the cat to a veterinary hospital for examination to find the cause and apply proper treatment based on it.
