So I watch 2 cats - Amber and Zoe.  Zoe has some kidney problems and needs subcutaneous fluids.  She was getting them twice a week, then daily, now every other day.  Throughout this time she does her best to hide from me.  Sometimes she just tucks her head under things and she is easy to spot.  Other times... not so much.  Here are the some of the places that I have found her...
