Not all vomiting is caused by hairballs. Here’s a quick comparison to help you figure it out:

|---|---|---|
| Frequency | Occasionally (every 1–2 weeks) | Frequent (multiple times per day or over days) |
| Appearance | Hair, usually long and tubular | Yellow bile, undigested food, foam, or blood |
| Timing | Morning or after grooming | Any time, often after eating |
| Appetite | Normal before and after | Often reduced or absent |
| Behavior | Alert and playful | Lethargic, hiding, or uncomfortable |
