Hi, I had a similar situation with Milo a few months ago. Vomiting clear liquid can indeed indicate mild stomach irritation, but sometimes it can also be a sign of dehydration.
The advice given above is good—keep a close eye on whether he’s drinking normally, and if the symptoms persist for more than 48 hours, don’t hesitate to get him to the vet quickly. Cats often hide their discomfort, so it’s better not to wait too long.
Hang in there, and keep us updated!
Honestly, your post is ringing a few alarm bells for me… I’m not trying to scare you, but the combination of behaviour changes + vomiting + loss of appetite really needs to be taken seriously.
The fact that he’s vomited clear liquid could be "nothing much" (empty stomach, a bit of irritation), but what makes it more concerning is that he’s less keen on his food and he’s hiding away more. Cats often do that when they’re feeling poorly.
Things you can check right now:
Is he still eating a bit, or hardly anything at all?
Is he drinking normally?
Is he lethargic or just a bit quieter than usual?
Has he been sick again since?
If his behaviour has been different for two days already, personally I wouldn’t hang about. In cats, a loss of appetite that lasts can quickly become a problem.
In the meantime: leave him in peace in a quiet spot, offer him some tempting food (warmed-up wet food, for example), and keep a close eye on him.
But honestly, if things don’t improve quickly or if he seems "not himself", a quick check-up at the vet is definitely worth it for peace of mind.
Please keep us posted 🙏

Hi there,
Vomiting clear liquid can be down to a simple digestive irritation (an empty stomach, mild gastritis…), but the fact that he's eating less, is less active, and is hiding more suggests he’s probably not feeling himself (discomfort or pain).
If the symptoms persist for more than 24–48h, or if you notice other signs (more vomiting, diarrhoea, marked lethargy, or a refusal to eat), it’s really recommended to see a vet quickly. A prolonged loss of appetite in cats can become problematic quite fast.
In the meantime, it's important to keep a close eye on him: monitor his food intake, any further vomiting…
If you're in any doubt or if he doesn't improve soon, don't hesitate to get him checked out.
Have a good day,
Maëlla
