"after coming from out of town to stay with their grandmother."
I'm assuming this means this was the grandmother's house they were staying at?
I work in hospice and and it's not uncommon for a family member to have multiple cameras set up in an elderly loved ones house for safety reasons. Maybe she wants to remain independent, but is a fall risk. We've had patients refuse in home caregivers, but allow family to put in cameras to watch for falls.
I'm also allergic, so I buy stupidly expensive cat food that reduces the enzyme in cats saliva that most people react to. I'm good to cuddle and pet my cat, as long as I can avoid scratches, I'm good.
