Why appetite matters so much in rabbits
Rabbits rely on a continuously moving digestive system, and a drop in food intake is widely recognized as a readable early sign of trouble (House Rabbit Society, RWAF). Noticing small changes before things escalate is the key.

5 things to check
- Food intake: has hay or pellet consumption dropped sharply over the last several hours?
- Droppings: fewer pellets than usual, much smaller, or misshapen?
- Abdomen: looks bloated and taut, or your rabbit reacts to gentle touch?
- Posture and movement: hunched and still, possibly with a grinding tooth sound?
- Whole body: drooling, runny nose, or ears feel cool to the touch?
If any of these stand out, it's generally better to reach out to a vet rather than wait and see.
What you can reasonably do at home
- Offer water little and often, using a syringe near the mouth if needed
- Keep the room away from temperature extremes (20–24°C / 68–75°F is commonly suggested)
- Do not force-feed or medicate without veterinary guidance
Picking the right vet
- Confirm in advance that the clinic handles exotic animals or specifically rabbits
- Know where you would go for after-hours or weekend care
- If you don't have a regular vet yet, building a shortlist via public clinic directories while your rabbit is healthy makes emergencies much easier

Everyday prevention
- Make hay the foundation of the diet
- Keep a rough feel for how much water and food is consumed daily
- Log weight, droppings, and appetite consistently so small changes stand out
The usagi Diary app lets you record weight, food intake, and droppings in about 30 seconds a day, so subtle shifts become easier to notice.
