While I have seen corpse pictures on forums for cats and dogs, I think I see it more on "exotic" pet forums, like guinea pigs, rats, mice, lizards, snakes, and spiders/insects. It's distressing regardless, because that was someone's beloved pet, but also no one needs to see their corpse; a pic of when it was alive is perfectly acceptable when discussing grief. I just don't see the point of posting a picture of the corpse, it just feels unnecessary.

I have had pets pass away, and I wouldn't even think of taking a photo. It just feels so weird to me. Im not the OP of this post, but I get what they're saying.
