Pet Care Needed

I have an older Maine Coon mix cat, Nala, that needs medication and overnight companionship. She gets stressed when shes alone for too long or overnight, and the stress can make her sick. My apartment is on the 3rd floor, so stairs are required. Her medication includes a probiotic powder mixed in food and occasional nose drops for congestion. I have a lot of trips planned in the 2nd half of the year, and Im looking for someone who can be available for the majority of my trips so she has familiar companionship.
