Hi, I have an about 6-month-old cat, Tostada. He's a mix of outdoors and indoors. Today, he came back in with what seems to me to be a broken arm and injured back. I'm a broke college student, so I have very little money. I don't know what to do, and I know treating this will cost a lot of money. Usually, he's so active and full of joy, but he's just been sleeping all day. Can anyone help?
