Safe to Monitor at Home

An isolated incident of vomiting (e.g., a single hairball or eating too fast)
The cat is still eating, drinking, playing, and acting completely normal otherwise
No blood or foreign objects present in the vomit

In our experience

In our experience, waiting more than 24 hours when a cat cannot keep water down is highly dangerous due to the risk of severe dehydration. When in doubt, call your emergency vet.
