That is very frustrating! I got on vacation twice a year and my Napoleon is at the office, so I always have others watching him. First thing, I put food in a medicine dispenser container so there is no overfeed. Second, I actually put LESS food in it that I would normally feed because I will not be there to do water changes. Third, I don't expect a pet sitter to water change at all, so I will not leave an uncycled tank in someone else's care. For my home fish though, I just leave them for the week. I've never come home to an ill fish doing it that way.
With my very first betta, several years ago (before I knew anything about betta care), I left him in the care of a coworker and she fed him black pepper, which killed him. I think it was intentional despite what she says, but regardless, I started using the medicine container to make it fool proof.
Littleman - - I think I would just lose my mind if I had to see the remains of my cat on the road. I lost 2 animals a year apart while in the care of others on vacation but it wasn't the fault of the caretakers. Both of them had to be euthanized 2 days after we got home. They died a year and a day apart. I wish they had notified us that they were unwell, but they didn't so it is what it is. I was terrified to go on vacation and leave my babies behind again after that :(
