VETERINARY SCIENCE!!!
In the last year, Scarlett's old tom cat has begun to move around a little more slowly. She's noticed lately, though, that he seems to be limping, favoring his left hind leg. Scarlett takes her cat to see a veterinary scientist, who does an examination. He tells Scarlett that it looks as if the cat has developed osteoarthritis. Scarlett is confused. Which statement BEST describes the tom cat's condition in layman's terms?
A bone has fractured and caused swelling in his hind leg.
An infection has caused pain to the tissue on his leg.
His joints have rubbed together so much that they are causing pain.
There is nerve damage to his leg, so he has lost feeling in it.
