An old image of SCP-5555 by a window inside of a house during initial containment.
Special Containment Procedures: None
SCP-5555 is to be kept in a 5x5x5 meter secured chamber in high-security Sector 3 at site 19. SCP-5555 must have 24/7 monitoring by two researchers and three security personnel. SCP-5555 is to be fed through a food slot every night between 8 PM to 9 PM. The containment crew asks to not do it before or after this time, as this is the time when its food would arrive.
Description: SCP-5555 is a cat, it’s breed is American shorthair. It seems as if it is 1-2 years old, and it seems as if it can’t age. If a human is put within a 10-meter radius of it, in the same room, it will attack said human, often killing them. SCP-5555 will kill people by [REDACTED]. SCP-5555 has been proven never to spare anyone.
Everything below is as of Addendum-5555-D
SCP-5555 can sloppily write in german. The o5-Council has approved Dr. Lights' request to stop human tests, however, animal tests will continue. It appears as if SCP-5555 has been growing more tired, investigations are pending.
Addendum 5555-A: A list of all the test logs are listed below.
Test log 1:
Subject: D-7464
Results: After the D-Class was put in the chamber, the door was closed. A few seconds after the door closed, SCP-5555 killed the D-class.
Notes: Doctor Carver fainted during the test and was immediately taken to the medical ward.
Test log 2:
Subject: D-7567, D-7484, and D-3744
Results: The three Class-Ds entered, and after the door closed, D-7567 was killed. D-7484 and D-3744 panicked, but SCP-5555 soon killed them too.
Notes: [REDACTED]
What the hell, Bright. That joke was not funny.
Test log 3:
Subject: A British shorthair 4-year-old cat
Results: The cats meowed at each other, and after 3 minutes the British shorthair was extracted.
Notes: It seems as if SCP-5555 only attacks humans. Further testing required to see if this is true or not. However, the cat did seem a bit agitated after the test.
-Dr. Carver
Test log 4:
Subject: A 5-year-old Pomeranian dog
Results: The two animals ignored each other. After 2 minutes SCP-5555 hissed at the dog, prompting the dog to freak out. After the dog was extracted, it attacked the personnel, resulting in its termination. Injuring Dr. Carver and minor injuries to the 3 guards.
Note: SCP-5555 possible cognitive hazard to animals, further testing will be done. Along with
human tests.
Test log 5:
Foreword: SCP-5555 had been contained in a bulletproof glass box with small breathing holes to allow D-7474 to hear it, but not be killed.
Subject: D-7474.
Results: D-7474 heard SCP-5555 meowing, and immediately ran out of the chamber before the door closed, killing one guard before being shot and killed.
Notes: We have to get faster closing doors.
Test log 6:
Subject: D-5778
Results: [DATA EXPUNGED]
Notes: [DATA EXPUNGED]
Test log 7:
Subject: British shorthair cat.
Results: The British shorthair attacked SCP-5555 and then was killed.
Notes: Dr. Light requested for the tests to be stopped. The o5-council is still debating this.
Test log 8:
Subject: D-76546
Results: As soon as D-76546 entered the chamber, SCP-5555 killed D-76546 and breached containment. Killing the 3 guards and Dr. Carver. Dr. Zuru barely escaped and was taken to the med bay. Soon MTF Eta-11 ("Savage Beasts") arrived and sent SCP-5555 to a temporary containment chamber.
Notes: Dr. Zuru has fully recovered. And this test was illegal.
Addendum 5555-B: SCP-5555 has been labeled as an auditory cognit hazard. During a breach in which SCP-5555 was trapped in a hallway, three D-Class escaping began attacking each other because they heard SCP-5555.
Addendum 5555-C: SCP-5555 tore off the finger of a Logistics Department worker while they were delivering food. They have been taken to the medical wing.
Addendum 5555-D: Dr. Zuru accidentally dropped a pen into SCP-5555s temporary containment chamber. It was shown to grab it by the mouth and attempt to write in german. It wrote, very sloppily: 'Hilfe.' Which is help in English.
Addendum 5555-E: No more tests are to take place, because we can't find out how to due tests without Class-Ds always dying.
Addendum 5555-F: Through the food slot, SCP-5555 was given a paper and pen. A conversation is recorded below:
Interviewed: SCP-5555
Interviewer: Dr. Zuru
Foreword: Just to state before the interview, a german translator was in the room, and everything has been translated.
<Begin Log, 5:55 PM, November 13th, 2019>
Dr. Zuru: Why did you write help when you first got the pen?
SCP-5555: I want help.
Dr. Zuru: Why?
SCP-5555: I do not wish to be contained. I want revenge on humanity.
Dr. Zuru: Why? What did we do?
SCP-5555: You killed my family.
Dr. Zuru: I didn't, but do you know who did?
SCP-5555: Yes.
Dr. Zuru: May I know their name?
SCP-5555: Their name is Jonathan ████
Dr. Zuru: You hear that?
Dr. Light: Yes.
SCP-5555: It won't be enough. All of humanity must be punished for other sins.
Dr. Zuru: But what are those other sins?
SCP-5555: How do you not know? All the killing? All the abuse? Every crime committed ever?
Dr. Zuru: Oh… I see now.
Silence for about 3 minutes.
SCP-5555: So, can I be let out?
Dr. Zuru: Ha! Of course not!
SCP-5555: Just you wait…
Dr. Zuru: Okay then. I will wait.
At this point, the interview was terminated.
<End Log, 6:10 PM, November 13th, 2019>
Closing Statement: The pen and paper were never recovered, and SCP-5555 has been writing on it more often. Dr. Zuru and Dr. Light have been thinking of an idea to better contain it.
Addendum 5555-G: SCP-5555 has stopped writing and stopped moving as much. When questioned about it, SCP-5555 said: "I'm tired." Dr. Zuru is looking into this.
Addendum 5555-H: SCP-5555 was killed during a Chaos Insurgency raid. Chaos Insurgents had stolen it, in a glass box. And a security agent threw a grenade, killing the insurgents and SCP-5555.
Greetings, authorized personnel. I'm sure you are wondering who is writing this. That does not matter, this must make you very sad. But I'm sure you translated the base64 and found out this is about the sixth test, which is expunged. The truth is, it never happened. Dr. Carver had a quota of 8 tests, so he made a false test, and threatened Dr. Light to not tell anyone. He told Dr. Zuru, so Dr. Carver broke the door system, which resulted in the doors, not closing which breached SCP-5555, causing incident-5555-A. Dr. Carver was killed by SCP-5555 during the breach. After this breach, Dr. Zuru replaced Dr. Carver. The way Dr. Carver found out about Dr. Light telling Dr. Zuru is that Dr. Zuru was helping Dr. Light in the SCP-5555s chamber, and Dr. Light told him. The next day the test happened, in which Dr. Zuru spectated. Of course, the breach happened during the test.
-Doctor.
Foreward: Only Security clearance level 3 are allowed to view this, the only exception are the people working with the containment of SCP-5555
The sound of the audio starting startles everyone in the room. But it's just audio, and then it goes quiet. Then the audio begins.
<Begin log>
"THE D IS DEAD AND ITS GETTING OUT! GET OUT!" - Dr. Light
"FUCK YOU LIGHT AND ZURU! YOU KNOW I DID SOMETHING AND NOW YOU WILL DIE" - Dr.
Carver
"LIGHT RUN-" - Dr. Zuru
The sound of screaming and gunshots are heard.
<End log>
"Soon enough Mobile Task Force Eta-11, Savage Beasts, arrived and attempted to contain it. 4 were killed, and 3 were injured. I saw the footage of the fight, it was gruesome. I won't show it, because I am sure you will be scared."
<Begin log>
It shows the inside of a helicopter, with Mobile Task Force Eta-11 ("Savage Beasts") inside it. The captain of the task force is telling them what to expect.
It gets fast-forwarded to them in high-security Sector-3 2 missing and they seem scared. Some screams and gunshots are heard.
It fast forwards about 3 minutes, to them hauling some bodies into a security room.
It fast forwards 5 minutes. SCP-5555 is in a soundproof glass box, some security officers are with them.
<End log>
"We must do our best to contain it. The thing killed 4 task force personnel, 1 of which due to the auditory cognit-hazard. And remember, Dr. Carver, betrayed us."
Closing statement: After the meeting took place, everyone went back to there duties. However, Dr. Zuru went to speak with Dr. Light.

Special Containment Procedures: SCP-7512 is to be kept in a containment chamber that is 2 meters in length, 3 meters in width, and 3 meters in height, with SCP-7512 being station at the farthest possible position away from the airlock. The entire chamber is to be soundproofed, with personnel observing in a separate chamber, with an airlock separating the two.
1 Containment Specialist and 1 Security Agent are to be station in SCP-7512s chamber at all times, on 8-hour shifts. During the hour of activity, an additional guard will be sent in to assist. Soundproof headphones are to be kept in a locker in the observation chamber, as to be used in the event of a containment failure. The chamber is located in Section C, Floor 9 of Site 11.
Description: SCP-7512 is a white refrigerator of an unknown make and model. SCP-7512 has two door handles, these act as handles from the fridge and freezer of SCP-7512. After a test, it was discovered that nothing is inside of SCP-7512, and can only be opened during the time it is active. (Put what it looks like).
Every day, at 1800 (6 PM) Eastern Daylight Time, through 1900 (7 PM) Eastern Daylight Time, a low drone noise is heard from the SCP-7512. The sound causes effects on everyone who does not have ear protection. All subjects who hear the sound when a test is not going on are to be removed from the area immediately and taken to the Floor 5 medical ward.
The effects of SCP-7512 are often present during the times listed below, but they will most often present right away. The observable effects last around 30 minutes, and the effects will stay for 5 minutes, but won't progress if the sound stops.
| Effects |
Exposure time |
| Slight headache |
0-5 minutes |
| Migraine like feelings, sensitivity to sound |
5-10 minutes |
| Loss of strength in legs, making it hard to stand |
10-15 minutes |
| Further loss of strength in legs, and arms, making it near impossible to stand, subjects become extremely sensitive to sound, subjects often become orally unresponsive |
15-20 minutes |
| Subject loses consciousness, subject may occasionally swing arm |
20-30 minutes |
| Subject suffers from cardiac arrest, all movements, brain activity, and heartbeat stop. No subjects have come back from this state, even after extensive lifesaving attempts |
40+ minutes |
As of now, SCP-7512 effects have been presumed to be cured with SCP-500, however SCP-500 is to not be used to cure effects, as they wear off after 5 minutes. It has also been proven that people who hear it through a recording or microphone won't be affected.
