I emailed them back and got off that mailing list, but the number stuck with me. I'd received a lot of info about my son's adoptive family when I was in the process of placing him, including their occupations, salaries, and debt. However, it had never occurred to me to even think about how much they were paying the agency, or the expense adoption must have meant for them.
I tend to think that particular laws and regulations have been less significant factors in the cost of domestic adoptions than broader technological, legal, and cultural changes, including the availability of effective contraception… the legalization of abortion… and the sexual revolution, all of which decreased the availability of adoptable children.
Usually, a shelter has already attended to the spay/neuter, the initial shots, and a veterinary clearance exam. If the cat's original situation left it with any medical challenges due to poor nutrition or neglect, these have usually already begun to be addressed by the shelter. You may get to play a final role in nursing your rescue back to full health, creating an initial bond between you both.
