My cat Gus came to my house a year ago he sleeps on our porch I can't have animals in side. I love him dearly I think someone poisoned him but I don't really know. He is bleeding severely from his rectum stumbling so bad he falls when he walks. He is moving a little more today and is eating now. But I'm still scared. I don't have to the money to take him to the doctor or I already would have. Someone please help me what can I do and what could be wrong.
