Fat or Sick?
My male mouse Flapjack after being hungry a couple of nights ago now eats like an elephant. His stomach looks swollen, but he keeps eating and eating and asks for more. He seems fine - runs on the wheel, cleans himself, but when he's sleeping, I can see his heart pulsating through the stomach, as if there's pressure on it. When I picked him up and touched on the left side of the stomach he squicked and jumped - in other words, he doesn't let me touch him on the left side. I can touch him on the right side through. I wouldn't say that he's constipated, because he poops. Not like he used to - everywhere and a lot, but he does poop. I usually give him oats, but on Christmas I treated him with a piece of honey cake. And after that it started. He keeps eating oats (no more cake for the fattie), and I give him carrots and lettuce and corn, and he eats a lot. Though this night I didn't leave a lot of food for him, and the swollen tummy and cold paws repeated. So is it how mice react on being underfed or it's a hidden disease?
thank you in advance!
