For standard Waggle campaigns, yes. 100% of all donations are used to provide medical care to the pet in question. For featured Waggle campaigns, the same is true until the funds needed for the pet's medical care have been raised, after which any excess funds are used to create grants to save additional needy pets in catastrophic situations and to support Waggle's mission to end economic euthanasia.
In some instances, veterinarian practices choose not to join the Waggle community (there is no fee to join), thereby preventing us from paying them electronically. In such instances, the fee that we incur to process and mail a physical check is deducted from the payment amount.
