Seeking a sitter near Silver Spring for 2 cats. Waste Cleanup: We have two litter boxes. Our diabetic cat, Casper, needs insulin twice a day after he eats. There are two feedings I will be unavailable: Wednesday morning, January 10 at 7:30 a.m. and Thursday evening, January 11 at 7:30 p.m. I can get his insulin ready ahead of time so you won't have to measure it out. Our other cat, Gizmo, does not need any special attention, just her meals.
