Here's the web site for this Animal Poison Control Center:

As is often the case, there's no free lunch ~ here are the costs associated with this site:

Non-Profit Funding
Our non-profit animal poison control center receives no state, federal, or hospital funds. In order for our veterinary staff to be available 24 hours a day to offer life saving advice, a professional fee is charged.
The consultation fee is paid by the animal owner, veterinarian or product manufacturer. Consultation fees are generally less than those charged by other veterinary specialists and combined with grants and donations allow the non-profit Center to break even.

Telephone Numbers/Fees
888-4ANI-HELP (888-426-4435)
$45.00 per case (VISA, MasterCard, Discover or American Express). The Center will do as many follow-up calls as necessary in critical cases, and at the owner's request will contact their veterinarian. The Center also provides via fax specific treatment protocols and current literature citations when indicated.

900-680-0000
$45.00 per case. The Center will do as many follow-up calls as necessary in critical cases, and at the owner's request will contact their veterinarian. These follow-up calls can be made by calling 888-299-2973.

APSS Products
When the call involves a product covered by the Animal Product Safety Service, the product manufacturer will absorb the cost of the call; thus there is no cost to the caller. Most APSS clients route animal calls directly to the Center. Feel free to call and inquire if a product is covered by an APSS client. http://www.napcc.aspca.org/apss.htm

I couldn't find a list of the companies that participate in the APSS program.

Thanks to Angie for finding the phone number!
