Kind of a long story.

Two years ago my sister and I went on a ten day trip. I had eight cats then and she brought her three cats to my house for our niece to come daily to feed them, change the litter box, and give one of my cats his meds. We called home a couple of times to check on the cats and my niece said that she had never seen all eleven cats at the same time but assumed they were all okay as food was being eaten and litter box used. When my sister and I returned home the cats were fine except we couldn't find one of her cats. We could hear him meowing for help and finally located him in the furnace ductwork! One of my cats (I knew exactly who the guilty party was) had taken the grill off a register vent and Sunshine had gone into the vent and apparently gotten lost in the ductwork. Thank heaven it was summer and the heat wasn't on! I screwed down all the register grills the next day.

So..........whatever your cat does while you're gone........it won't be that bad!
