I would assume nothing. I would not accuse.
I would just send a friendly message and ask if they’ve been getting on okay with the daily cat feeding. Thank them.
The thing is, sometimes people do slip in. It happens.
We have neighbours cat sit. I always send a friendly text after a couple of days. It works as a reminder in case they forget.
Once, the teen neighbour who was doing it forgot. It was luckily just a weekend. We didn’t know, but they texted to confess and brought a plant to apologise.
The other thing we do as it’s friends, is leave choc onthe table as. A thank you. If they were still there on our return, I’d be a bit worried.
If it’s someone’s job, not turning up is very bad. With a. Friend or neighbour, to be honest, it’s easy to forget, so I think tactful messages are a good idea and probably actually appreciated. If someone forgets one day it won’t be the end of the world.
And I hate the ring doorbell. We fed someone’s rabbit once. I really didn’t like them knowing the exact time we visited. Sometimes we would go at midnight if it suited us. Other times we might go at 7am. The person commented which showed they’d been watching us on their doorbell. It made me feel uncomfortable. Doing a favour doesn’t mean you then have to go at the exact same time every day and it really won’t matter for most pets if you’re a few hours different.
If you need a very specific timing, you do need to pay someone. And obviously they should go.
However, with all these kind of complaints, it’s often best not to start with accusation, but a query. Often, there is an explanation…you just don’t know it. Save goi g berserk for never…or at least when you’ve heard some detail.
