My daughter uses petsitters
She has 100% indoor cats. She leaves detailed instructions for the petsitter. She uses a small company and doesn't get the same person all the time. She likes the sitters who rinse the cans and used plates, and runs the disposal so the house isn't smelly when they get home. The service has the client leave instructions on the website. When you get to billing, my daughter said she got a bill before she got home, and waited to pay until she saw all was well. The petsitting company sent her a reminder while they were still hours away from home.
My daughter likes petsitters who send a daily report, with pics (if possible). She recently set up a camera, so if the petsitter doesn't see the cats, they will show up on screen when the petsitter isn't there. It gives her peace of mind.
I hope this helps.
When I needed petsitters, I hired neighbors who liked pets. Didn't work out that great 3 of 4 people. I didn't travel when my pets were elderly. I didn't want anyone to stress if the kitty passed while I was away.
