They both went to the VET.
This visit was for recheck for both Goro & Niko.
Goro for blood work as his BUN has been slightly high.
Result: Still at the same level. Will keep monitoring.
Niko for heart murmur as it was detected at last checkup.
Result: Murmur still heard. Later he was taken to cardiologist.
Turned out it was innocent (physiologic) murmur. Phew!
Now we can relax until next time we go to V...
