I do, because I have to...but I did leave my older cat (she was 13) in the care of a pet sitter....and she died suddenly and mysteriously while I was gone. Then, I left the kitten and puppy with my husband who left them with a friend for a day and they lost the puppy...for two days.
I was a wreck. My horse is always in somebody else's care right now. I have contemplated sending her to a different trainer or moving her to a different barn, but the one's she's with now I know and I don't really know all that many others.
But I always worry and fret before and during the time I'm gone. I make lists and leave cash and instructions and extra supplies...sigh.
