So, I've been on a little abandonware kick ever since I found out the original Viva Piñata is abandonware and I've made some interesting discoveries.
Jaws Unleashed (Hard Vore):
https://www.myabandonware.com/game/jaws-unleashed-cn4 This game was already mentioned here before, but I'm bring it up for anyone who wanted the play the game. It's Jaws, so expect a lot of hard vore.
Axysnake:
https://www.myabandonware.com/game/axysnake-iigLike most snake games, you're eating fruits and not animals but this game deserves special mention for a few reasons. This is a 3D snake game and the game actually has an unusually good bulge system for when you eat. Not only do bulges flow seamlessly through your snake, eating in rapid succession gives you bigger bulges and every so often your snake will let out a wet belch that starts off as a bulge coming out of its body. Even your snake choking on a rock is pretty punchy.

Also, the game's play area is surrounded by shadow creatures that will eat your snake if its head touches any of them . This death animation shows your entire snake getting quickly pulled into the shadows and no matter how long you got.

Warning: Some people have said that the death scene scares them so be warned.)
Feeding Frenzy:
https://oldgamesdownload.com/feeding-frenzy/ - Please read the spoiler before getting this game.
Pretty sure most people know about this Popcap game, instead let's focus on the potential virus this game might have. The myabandonware site admin stated that their earlier version was flagged with a lot of viruses but they were able to find a new cleaner version. Their new version still gets flagged for a few viruses by two vendors and some people say that the oldgamesdownload version is cleaner. Yet, their version also gets flagged by one vendor stating its an browser manipulator. Now, both versions could be getting false flags from some lower-end security vendors. But, ultimately, if you want to truly be safe either play these on a virtual machine or just buy the sequel off Steam for like $5.
These last two aren't abandonware, nut here they are regardless.
I of the Dragon (Hard Vore): You can get this on Steam, Zoom, or GOG. Right now, Gog has it on sell for $2.39 until the 4/25.
You play as one of three dragons destined to save a human kingdom from a demon. Every so often, you'll get hungry and will need to grab an an animal or monster to eat. While the eating animation is pretty basic, the noises and sprays/mists of blood during the eating animation gives off the impression the prey is being violently ripped apart. Also, whatever you eat tends to cry out in pain during the process and larger creatures take longer to eat.

Dragon Rage (Hard Vore): This is an old PS2 game, I don't think it's ever be rereleased anywhere.
