If you see an abandoned and/or otherwise abused, or deceased pet, consider that he or she could be or could've been be lost (e.g., escaped from a backyard and with concerned owners looking for him or her) or stolen. Please have him or checked for a microchip and/or a collar, and/or otherwise try to locate his or her potential owners. e.g., A couple in Pennsylvania was wrongly accused of abandoning their four-year-old Shitzu by putting him in a crate and having him freeze to death. In the Facebook post re that matter, one of the couples' neighbors said that they recognized his "I LOVE LONG WALKS" collar and were "devastated".
Same with other apparently-neglected/abused pets: the owner(s) might have disabilities (including invisible illnesses) and be unable to care for the pets, all while (s)he gets or they get demonized instead of have somebody to help him/her/them care for them. Please for God's love, don't bar those of us with disabilities like Depression, OCD/Anxiety (which can bring about hoarding), ADD, and Cerebral Palsy (all of which I have) from owning pets. Don't especially the "Adopt; Don't Shop" types demonize people with disabilities enough, and notwithstanding that our medical providers—e.g., my physiatrist at the time—recommend that I don't adopt—and my physiatrist had her reasons for doing so. By the way, she is now a researcher at NIH—and where are you "Adopt; Don't Shop" types in life?—and I mean besides sitting behind your computers, marching on the streets, and/or doing something else at God knows where to spread more ableism, assuming that everyone can and/or should adopt (and not that you've ever really considered us people; but hey.)
Also, you "Adopt; Don't Shop" types of course demonize legitimate breeders by conflating them with puppy millers partly or even entirely because of your ableism—and you "Adopt; Don't Shop" types who are also people with disabilities are hypocrites and obviously self-hating PWDs—and I know that PWDs, let alone "Adopt; Don't Shop" types whom are PWDs, are not immune to ableism especially since society has tried to ingrain it into us since the time that the first person who had a somehow-noticable disability existed, and you're still supposed to try to fight both ableism and intra-ableism instead of buy into it.
Speaking of buying and adopting instead of shopping, maybe you "Adopt; Don't Shop" types should—if you can—try to adopt attitudes that involve critical thinking, compassion, and empathy—none of which anybody can buy, since critical thinking is an acquired skill and values such as compassion and empathy are learned (not to mention that, e.g., especially quite a few rich and famous "Adopt; Don't Shop" types don't have those values in the first place, anyway—no matter how much they fake that they do, particularly when it comes to us PWDs and the other less fortunate among us.)
PS Having Reilly (See below.) has saved me from having my life taken by Depression—and were Reilly not in my life, I would've died from starvation due to oversleeping (since I naturally wouldn't have been awake and thus able to eat)—and Reilly is one of the reasons that I am alive in the first place.
