Poor Kodak! I can see that his abdomen is distended and that he is hunched with his fur erected. The latter two are signs of pain, as well as the increased aggression. I recommend having him seen by a vet as soon as possible to determine the cause. His abdominal distension can be caused by a mass or an infection, a foreign body, or enlargement of any of the abdominal organs.
