You know how humans get bad injuries in a joint and later on when the weather gets wet or cold it aches? Can that happen in cats too? One of my cats had what we thought was a broken paw when someone found her in the garbage (she was a week old). She limped when she first walked, but the limp went away. Now that it’s so wet and cold, she’s limping on the same foot. It’s a slight limp, but she puts the paw up when she stops walking.
