I received this helpful note from a reader:

Hi, I work at a Poison Control Center for people and we get a number of calls concerning animals (for which we have little knowledge so ultimately refer them to vet or Animal Poison Control as you mentioned above). Just thought you might want to know there is another animal help phone number –the Pet Poison Helpline –they also charge a fee ($85) and their phone number on the website is (855) 764-7661. Many people can’t or won’t pay that fee so I also direct them to another option that might be more affordable option of a online chat service with a Vet/poison specialist–that is called “Just Answer Pet Poisoning” … and that has a service fee of $35.

Thank you to the kind person who sent this advice.
