What on earth were these pet owners doing expecting you to look after their pets while you were going through so much family distress? I hope they were atleast paying you.
Kind of a situation where no one else know what others were doing;
My parent's neighbor with a dog asked me to house sit with the dog thinking I'm at my parents all day anyway, but I'd have a private place to sleep nextdoor - sleep WITH the dog that is, that was the whole point of staying there - the dog can't sleep on it's own = spoiled.
Once I committed to that, another friend says he's got to go away for a couple weeks on business and could I stop in for his cat, so it wasn't far and I agreed.
Then this guy John (with 4 cats) has this medical emergency and is rushed from his work to the hospital - get called to take care of his cats (I'm the former landscaper and still have keys to the house) - but on THIS date, one cat has a Dr. appointment and I always remember driving around to different vets (because I didn't know the cat's current vet), carrying the cat carrier in the pouring rain. I finally found the right place, but then there was a 4-hour wait!
And that was just the beginning, John was in and out of the hospital, but he had a surgery on some sort of hernia rupture so he couldn't care for his cats no less himself. So I was taking care of his cats and him for almost 4 months - which overlapped my other pet care duties.
This all kind of got dumped on me at a time when I'd told John I was too tied up with my dad to nursemaid someone else, but he made no plans when he had a chance and just relied on me - which made me feel I'd had about enough of him.
Another confession why I didn't just tell John he was on his own:
1. I really couldn't leave him in the lurch while so helpless and trying to recover, and he was the widowed partner of my former friend, (they sent him home about 4 times after which he'd have to go back to the hospital due to hemorrhaging & to have this stomach pump thing checked - it had an awful alarm on it! They never should have sent him home the first three times, esp. when there was really no one there to care for him.)
2. I did care about his cats (I'm not a total beast)...
3. But here's the clincher - since he'd just had a major surgery, the doctors were loading him up with month's worth of percocet where he was allotted like 6 a day, but would only take 2 a day - and I was getting the scraps!
P.S. They did all pay and John paid in more than just more, but opioids!
