Answer

Because of their small body weight, cats do very well after the loss of a leg. Their human friends often take longer to adjust to the change than they do. It might help, however, to make the cat an exclusively indoor cat. It’s reflexes and ability to avoid predators may be a bit hampered. Another helpful move might be to provide a few stools where the cat chooses to get up and down from things, such as beds or a favorite window sill.

If a front leg has been removed, jumping down can be painful if one leg has to catch the fall from three or more feet up. If a rear leg is missing, it may be difficult to provide the torque to jump up onto high things without a stool halfway.
