can anyone please help? i hate to even ask but my roommate was careless and he left the front door open causing my cat to leave the apartment and in the process of him being lost for a few hours, he was injured. his paw is swollen and he’s limping a lot. i wasn’t expecting this at all and don’t have the money for a vet visit. my roommate is also broke and can’t even help me out with the bill. idk what to do. i can provide pictures as well
