I feel so sorry for the animals in this situation. I rarely travel but when I do, I've used a co-worker, friends I could trust, or my roommate who would be living with my cats any way. I always go over everything a fews days before I'm going to leave and I write down all of the information,my contact number, vets number etc. I'm usually not gone for any length of time so I usually don't call. I guess I just assume that they'll call me if something is wrong. So far I've never had any problems.
