Rat poison
Also known as: rodenticide, rat bait, warfarin bait, bait blocks
How dangerous is it?
This is an emergency
Do not wait for symptoms. Call us now on +853 6677 6611 and head to the clinic. Bring the packaging or a photo of what was eaten.
Signs to watch for
- Signs and timing depend on the active ingredient, so identify the bait
- Anticoagulant baits: often no signs for 2 to 5 days, then bruising, pale gums, bleeding or laboured breathing
- Bromethalin: tremors, agitation, weakness or paralysis within hours to a few days
- Cholecalciferol (vitamin D): heavy thirst, vomiting and kidney failure over 1 to 2 days
What to do
Come in immediately, even if your pet looks fine: early treatment is simple, late treatment is intensive care. Bring the bait packaging if possible.
Macau note
Municipal and restaurant bait stations exist across Macau back lanes. Rat poisons are not all the same: anticoagulant, bromethalin and cholecalciferol baits each need completely different treatment, so the packaging or a clear photo of the bait is essential. Keep dogs leashed near bins and report chewed bait boxes to us with a photo.
