Veterinary notes and prevention

Anticoagulant types respond to vitamin K1 over several weeks; bromethalin and cholecalciferol products need different, more intensive management.

Prepare the information your vet needs

  1. For Rodenticides (rat and mouse poison), report the exposure route: Eating bait directly, or eating a poisoned rodent. Tell the clinic the time, possible amount and your pet's species and approximate weight.
  2. Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
  3. Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
  4. Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
