Pet Walker - Full-time / Part-time

My cat 6-year-old cat just got diagnosed with diabetes so she needs insulin twice a day. I currently do 7:30a and 7:30p but I can start adjusting that time now if it needs to be earlier or later. I need someone to come out Friday night, both times Saturday and Sunday, and then just Monday morning to give insulin shot. She takes 2 units its a very small amount and then also just check her food water bowl and littler box. Will only be at house for like 5 minutes each day no one needs to stay with her
