Anyone else's parents abuse animals, too?

My mom is a malignant narcissist, and she is a sadist. I didn't realize how bad until last year when I started getting help. Besides realizing she enjoys seeing me suffer (especially if she inflicts it), I also realized she abused the animals to hurt me. I used to think she was just crazy. Hyper controlling. Anything. Now, I realize it was more than that.

She used to physically and sexually hurt me when I was little, but as I got older, that was harder for her to do and still be able to hide it. So she turned to hurting the animals more. She already abused them sometimes on her own, but she definitely weaponized them against me because she knows that it will hurt me to see the animals suffer.

Things I've seen her do (TW: Animal abuse):

• Physical abuse of animals but rarely ever enough to leave lasting damage. Although there are times I look back now and wonder if she is the cause of some injuries. She recently had one of her six cats die, and it died from a spinal injury. Her reaction to its passing was muted (not unexpected) but with even less fake grief than normal.
• She would frequently put the animals in dangerous situations, like let them outside when we lived in unsafe areas or lock them outside under the porch which was also unsafe especially in the winter. I realized she did this mostly to watch me squirm because I was worried about the animals. I had one cat she let out like this that got shot by a neighbor. That cat lived but became a tripod. My mom threw her outside again a year or so later, and the cat got mauled by coyotes and died.
• She straight up killed many small animals. Fish, birds, small mammals, reptiles, amphibians. Actually, I don't remember a single small animal I had that she did not kill. They were usually "on accident." She'd put reptiles next to the fireplace, birds next to drafts, overfeed, or sometimes just straight up admit to killing them unapologetically saying "You don't need them." or "They were disgusting."
• She would shave or otherwise alter pets sometimes to get at me. She shaved our collie once. For those who don't know, collies are double coated dogs. They aren't supposed to be shaved. There was no reason to shave him, either.
• She often gave away pets I loved for no reason. At least, I hope that's what happened to them. In retrospect, with everything else, it worries me now.
• Lots and lots of animal neglect. She would barely ever buy proper food, and for most of my life, she refused to take animals to the vet. Beyond food, caring for animals' other needs was never even a thought for her. We had three beloved dogs once that she refused to take care of anymore because "They're happier running wild."
• If it wasn't neglect, it was obsessing over them. She overfed her favorites but offered no training or other care. They became little monsters that were 3-4x what they were supposed to weigh. Often, she would use overfeeding them to get at me, too, since she restricted my food. She tried to do this again recently. She invited me to visit her. I was hesitant because she was being... well. Worse than normal. She made a giant lasagna. Like one of those giant pans that barely fits in the oven. It was supposed to be for me and her. I got worried and flat out refused to go. She took the entire tray of lasagna, scooped it into two giant bowls, then she gave those two giant bowls to her dogs. This was enough food that they definitely would get sick. She took a blurry, shaky video of the dogs eating the lasagna out of these bowls. For some reason, her entire house was dark, and she was laughing. It was completely unhinged.
