I am a retired caregiver. In addition to being a human caretaker for the last seven years, have also been a pet companion for the last ten. After all, aren't our pets family?
My goal, as a sitter, has always been to hear my client say upon their return home: "they (pets) didn't even miss us! it was like we had never left!" My intentions when I care for a trusted friend is to keep ALL routines exactly as the owner would do them were they in the household. Each detail is important so that your friend has very little change to his/her routine.
My specialty has always been overnight care as these are the families who understand the traumas associated with boarding and the abandonment pets experience when left behind.
