I saw a pamphlet at the pet store about an organization that helps pet owners afford cancer treatments for their pets :smile: It's called The Dog and Cat Cancer Fund, http://www.dccfund.org/ They are a need-based organization and do have to verify income before helping an pet owner in need.
The Animal Cancer Foundation also keeps a current list of organizations that help pay for veterinary oncology treatment. Most require a referral by a board certified veterinary oncologist and are need based and verify that before giving assistance. A list can be requested at info@acfoundation.org.
