What's usually genuinely fine
- An occasional hairball, especially in longer-haired cats
- A single episode after eating too quickly
- One-off vomiting with a cat who's otherwise completely normal afterward
What's worth actually tracking
Frequency is the real signal, not any single episode. Vomiting more than once or twice a month, in a pattern rather than a one-off, is worth mentioning at a routine visit even if each individual episode seems minor.
Worth knowing: "my cat's always been a vomiter" is one of the more common things vets hear, and one of the more commonly overdue-for-investigation situations, precisely because it's been normalised for so long.
What needs same-day attention
- Repeated vomiting within a single day
- Vomiting alongside lethargy, not eating, or visible pain
- Any blood in the vomit
- Retching with nothing coming up, especially with a distended abdomen
This guide is for information only and isn't veterinary advice. Any of the above warrants contacting your vet promptly rather than waiting to see if it resolves.
Why the pattern is the part worth keeping
A single vomiting episode is forgettable, and that's exactly the problem, three of them over two months looks very different laid out together than it does scattered across separate half-remembered days. Halo's daily log is built to hold that kind of easy-to-dismiss detail until the pattern actually matters.
