Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry that Sasha is so ill! Based on your pictures Sasha looks very sick and very thin. Possible causes: infected uterus since she is not spayed, cancer, foreign body (ate something that is stuck in her stomach or intestines), or intestinal parasites. I would need more information about what tests your Vet ran: blood work, stool sample or X-rays of her belly? If those things have not been done then I would recheck with your Vet as soon as possible. An infected uterus and a foreign body are emergency surgeries and can be life saving if done early. If she has cancer the best thing would be to discuss humane euthanasia since Sasha is suffering. I am very sorry and I with you and Sasha the best.
