What a rotten '05 you had!
You *have* changed the locks on your doors since 2005, haven't you? And you have homeowner's/renter's insurance, yes?
10 minutes to drive each way is NOTHING. I would do that for a friend in a heartbeat, and I say "no" to things easily. Hanging out with cats but not having to live with them (I like having
outdoor cats but doubt I will ever have one as an adult unless I own a farm or live rurally, which I don't want to do)? Perfect. Feeding fish? Easy. Turning lights on and such? Simple. 20 minute drive? Cakewalk.
Just ask her. Or you could be circumspect and talk about your problems of who is going to watch the cats, and maybe she'll offer. Sometimes I do that method accidentally.
When I was a kid, I watched our neighbor's poodle when they were away, but it was a nice little street, without partying teenagers or absent parents. My mom was there to make sure I went over, I never brought anyone else there, I was safe. It does NOT sound like those are the neighbors you have, so forget the neighbors.
And the other option is that fish-feeding timer someone mentioned, or the dissolving thing, and to board the cats. When we boarded our now late cat during our 17 days away destination wedding, then honeymoon, she was SO happy. She had attention all the time (by non-allergic people who didn't do rude things like have asthma attacks), she got brushed a million times (by people who didn't have to wash their hands arms and face immediately afterwards), she was treated like even more of a princess than we did (this was at the vet's office's boarding facilities). I think she was angry she had to come home to her normal people.
