Poor Baba. Without more information it's not possible to determine what has caused Baba’s condition. However, it is essential that Baba see a veterinarian immediately. He sounds like he is seriously ill, and there are various reasons that may have lead to his sickness. Diseases such as kidney disease, hyperthyroidism or diabetes are possibilities, as well as potential bacterial, parasitic or viral infection, trauma or toxin ingestion, or a neurological or muscular disorder. Please take Baba to a veterinarian immediately, as he sounds very unwell. They will let you know about their recommendations for diagnostics and treatment based on Baba's condition, and can guide you through the process if you elect to euthanize.
