Traveling

Hello, my female cat is 16 years old. She is very needy and hates when i go away for a few days. In the past year her blood test have shown high calcium which the vet says could mean several different things. She has lost weight from 11lbs to 9lbs. She eats much less than before. But other than that she is still thriving, likes to play just looks skinnier.

My question is that is it ok to leave my cat alone for 4 days? A vet tech will be stopping in each day to check on her but wouldn't be there long. I always worry about leaving her but now that she's older wondering if 4 days is ok???

Also, anyone have a cat diagnosed with high calcium levels? Advice.

THANKS!
