The purple comb most likely indicates low blood oxygen levels. If she isnt struggling to breathe, its most likely major organ function rather than a respiratory problem. The swollen back end kinda confirms this. The swelling is likely fluid retention from organ failure. The heart is a main culprit, but not always. The fluid can also be putting pressure on organs causing a never ending cycle, as well as pain and suffering. The pain can add to her acting sickly and not wanting to eat too. You can drain the fluid and it should give her some relief. Looks can be deceiving. It may seem like it's not alot, but a few cups or more of fluid could be hidden in there. Especially if the pressure is going backwards into her body cavity and organs, as opposed to bulging visually outside of the body.
