Poisoning in pet rodents

What to do if you think your pet rodent has been poisoned:

  1. Stay calm. Remove rodent(s) from the poison source.
  2. Contact your vet immediately; inform them when, where and how poisoning occurred. If appropriate, carefully take the packaging/plant/substance to the vet. Don¿t expose yourself to any harm.
  3. Follow veterinary advice. If you¿re advised to take your rodent(s) to the vet, do so quickly and calmly.

Never treat/medicate rodent(s) yourself. Some medicines for humans/other animals may be poisonous to rodent(s).

If skin/fur is contaminated, wash with mild shampoo and water, rinse well and dry.

Keep rodent(s) away from any other animals to avoid cross-contamination.

Never `watch and wait¿. If you suspect your pet has been poisoned, contact a vet immediately.

Preventing poisoning in pet rodent:

In the home:

  • Keep houseplants where rodent(s) cannot reach them. Collect dropped leaves/petals.
  • Keep pesticides away from areas rodent(s) can access.
  • If treating pets with insecticides, separate them from other pets.
  • Keep an eye on your rodents.


  • Ensure housing/exercise areas are free from, and not overhung by, poisonous plants.
  • Ensure rodents¿ water supplies cannot become contaminated, change regularly.
