Does anyone know what can cause an 11 year old python to lose weight when never refusing a meal? She hasn't lost much weight but, the rodent size was increased. She is also very inactive and feels squishy as if she lost a lot of her muscle mass. She just seems weak and thin but, still has a very strong feeding response.*


I already had her to the vet multiple times. Her fecal and bloodwork came back normal.*


Is 11 actually old for a python? I thought they can go into their twenties. Maybe she is starting to die from just old age.
