The thing I can't help but wonder is whether it's watching the cartoon that contributed to them being ABDLs or if they're merely associating with it after the fact.
I remember awhile back on some atrocity tourism site there was a furry artist who had a fetish for the enlarged, thumping hearts that cartoon characters get when they're scared. That is so ridiculously specific it HAD to have been influenced by the cartoons he watched growing up.
