There are a few things that could be causing Chunnu's belly to be larger than normal. First, if she is having heart or liver problems, this can cause fluid to backup into the belly. This fluid can usually be diagnosed with x-rays or ultrasound, and if there is a large amount of fluid it can easily be removed. However, the fluid will usually come back in a matter of days or weeks unless we cure the underlying cause.

Another potential cause for a large belly is intestinal parasites. I recommend that Chunnu have a good dewormer or have her stool tested by a veterinarian.

The other potential cause is that she is gaining weight in fat. As cats age, they started to shift more weight to the belly and can appear bigger there than when they were younger.

If she is eating well and her activity is normal, you could just continue to monitor her belly from home, or see your vet for re-evaluation.
