A girl describes killing her dog, though we do not see it. In another instance the killing of puppies is mentioned. Both take place in the first episode.

In the beginning a deer gets hurt by the monster Geralt kills, it's laying down with a visible wound, and when the screen goes black he mercy kills it

Episode 3 a Witcher follows a trail of blood into a room with half cut dead pigs hanging from above, cut-off heads are shown.

In episode 4 and episode 8 In episode 4 horses are seen dead on the ground after a creature attacks a coach. In episode 8 a dead horse is seen before the opening credits.

In episode 2 it is mentioned that a girl (magically) froze a cat, though it is not shown and it is not said whether or not the cat died.

There are monsters with bug-like characteristics.

Death occurs offscreen, but body is seen and discussed

There are monsters with spider-like characteristics.

Eels are shown in episode 2, during a scene in a cave. They are the focus of the scene and very snake-like.

Not abused, but there is drinking (mostly Beer/Ale) and also discussed, no addiction

In episode 4 a man cuts a pieces of flesh out of his own arm and eats it.

There is a vivid scene in Episode 3 where Yennefer undergoes a ritual to turn her into an image of beauty. She refuses painkillers and is shown having her uterus removed and tossed into flames, so it's kind of like a torture scene in which she undergoes intense physical pain.

in episode 1 there is graphic discussion of people being burned alive (amongst other torture). episode 8, ~36 minutes in a woman is hurt by a burning torch held to her throat. episode 8, 50 minutes in, many many people are burned alive

Episode 4 Decapitated

geralt and jaskier are kidnapped for a brief while

A baby dies.

Many background characters cheat on spouses with more relevant characters. It's a topic that comes up a few times.

in episode 4 geralt is shown in a bath. there is no running water. he is shirtless and his nudity is implied, but nothing below the chest is shown.

specific jump scare ep 8, 2.5 minutes in, things jump out of the ground to attack geralt

I wouldn't say ghosts but there are monsters.

There is a mind control weapon at one point, and a character who shapeshifts into others.

In the background of some shots spitting is seen.

Episode 4 around 53:00 And before, when the queen jumps through portals.

No hospitals in this universe but there is medical/herbal/magical treatments

Not autism, no, but I feel it's worth mentioning that Yennefer was born with a hunchback, she is treated like she's "disfigured" due to the hump and her jaw being unsymmetrical, it seems to also be assumed that she is dumb or slow. during the time period, people that are different like a "defect" or "disability" are considered lesser people, disgusting and sold as slaves. Obviously, a hunchback isn't remotely like autism but the abilest bigotry is there.

Yennefer is frequently gaslit by her instructor in covert ways.

please learn what body dysmorphia means. definition: A mental illness involving obsessive focus on a perceived flaw in appearance

In episode 3, Geralt climbs into a tomb/sarcophagus and closes the lid.

We see someone jump from a window, as well as some people supplied with a potion to die in episode 1.

A girl attempts suicide by cutting herself in the beginning of episode 2 (before the opening credits). It is not shown, but her wrists are later shown wrapped with bloody bandages.

There is a monster that is described as an "overgrown abortion" which [spoiler] was created by a curse placed on the fetus of a dead pregnant woman.

No, but there are repeated discussions of infertility and forced sterilization which may be upsetting to folks who are sensitive to miscarriage (I sure was...)

We don't see it, but the death of a pregnant woman is discussed in episode 3.

Mentioned in Episode One

Mentioned only on the episode 3

Geralt is consistently hated and put down for being a mutant and Yennefer is insulted and attacked for a physical deformity and impoverished upbringing

In episode two, there is a scene with an introductory magic lesson. The only black student present is also the only character to be magically injured. She does not die.

episode 3 ****SPOILER AHEAD**** shows the physically disabled character being "cured" of her physical disability, changing into a "beautiful" physically abled character.

Cliffhanger

No cars in this universe

No nukes in this universe

Young disabled girl is treated unkindly by many, in a school type setting many teen girls are treated very strictly and not with much worth.
