Unreasonable to expect sitter to pick up after pet?

Hi group;

Is it too much to expect a pet sitter to leave your home the way they found it?

I hired a sitter from http://Rover.com to drop in on my cat while I was away for a few days over Christmas. The sitter had looked after my cat before, and I thought he had done a great job, so I hired him again.

Well, I came home to a mess this time. Things my cat knocked off a shelf were on the floor. My cat had knocked over his toy basket, so cat toys were all over the place. The small garbage can I keep secured in a cupboard (so my cat can't get to it) under the sink, was tipped over and garbage was all over the kitchen floor (and the cupboard door was open). To say nothing of the fact the sitter was TWO HOURS late for his booking Christmas Day.

A pet sitter's job is to pick up after a pet, isn't it (not just feed it)? Do sitters really need to be told to do this?!

I do pet sitting via Rover myself, and I'd be mortified if I didn't leave a client's home the way I found it.

Am genuinely asking myself in my stunned state if I expected too much!
