Special Containment Procedures
SCP-6710 manifestations should be monitored by the Mobile Task Force Delta-9 ("Katledoiscope Cloud"). In the event of an occurrence affecting a multitude of people, a process of disinformation and amnestization of those involved should be carried out as necessary.
In locations where SCP-6710 manifestations are more frequent, security perimeters should be established to ensure that no civilian witnesses SCP-6710 manifestations.
Description
SCP-6710 is a feline entity resembling a large Felis catus with whitish fur that inhabits the terrestrial troposphere1. It is able to levitate indefinitely by anomalous methods, with the ability to stay above the cluster of clouds. SCP-6710 has proven to be able to dematerialize and enter what has been called "Inactive State", and can stay in this state for approximately one to two years. When it enters "Active State" SCP-6710 appears in a location apparently selected2. 70 manifestations have been detected in the last 50 years.
The exact length of SCP-6710 has been impossible to determine due to the inability to approach it without disappearing; however, it is estimated that it can be 1.3 kilometers long. Attempts to view SCP-6710 using satellites and other methods from areas above the troposphere have resulted in blurred and inaccessible images. Through several interviewing sessions with SCP-6710, it has been determined that the subject is, to some point, aware of its environment and how it is affected by it.
When it approaches areas with an abundant human population, it has demonstrated to be able to pick out those who are able to visualize it, while the other subjects will only notice a cloud that they commonly describe as "Longer than usual". The way it chooses these individuals is still under investigation.
The Foundation's records and archives date the first sightings of SCP-6710 around 1950, when a sailor reported the sighting of "a huge cat in the clouds" off the coast of the United Kingdom. His companions denied it, explaining that the subject had spent "too much time in the solitude of the ocean". Other sightings have been recorded and dismissed as anomalous events until 1992 when a group of researchers flying from Florida to Madrid, Spain encountered the anomaly in the middle of the Atlantic Ocean. SCP-6710 held a stare at the crew and then disappeared.
Following the incident, the actual Mobile Task Force Delta-9 "Katleidoscope Cloud" was established, and a search was performed to find stories related to the entity. The only other recent sighting alive was Jacobo Acosta, a former lighthouse keeper who worked for 22 years at the isolated Les Éclaireurs Lighthouse, located in Tierra del Fuego, Argentina. Jacobo mentioned on more than one occasion having lived with "A Cat in the Clouds" during his stay in his retirement home in an Argentinean town. On April 5, 2000, researcher Ema Eiros was sent to interview to find the relationship between SCP-6710 and Acosta.
Addendum 6710-1
Researcher Eiros met with Jacobo Acosta at his retirement home, introducing herself as a reporter who wanted to document his case. The interview has been translated from Spanish.

Researcher Ema Eiros
E. Eiros
Good morning Mr. Acosta, I am glad you accepted my invitation for the interview.
J. Acosta
My pleasure Miss Eiros, when you are my age you need to see a young face once in a while. You never know when the last one is going to be.
E. Eiros
If you don't mind, let's start this interview as soon as possible. When did you start working as a lighthouse keeper?
J. Acosta
Yeah, well. I had retired from my sailor days, back in the '60s. I was about 45 years old, then a couple of years later I got that job. It was kind of quiet, and even monotonous. But after facing the aggressive sea, I needed a long rest.
E. Eiros
Well, I'm surprised you worked so old. When were you retired from your position?
J. Acosta
I retired in '85, 22 years of service. I would have wanted it to be thirty.
E. Eiros
Did you like that job?
J. Acosta
I was raised not to be useless. Although yes, it has definitely been the job that I have been most fond of.
E. Eiros
Well, what was life like at the lighthouse?
J. Acosta
Life at the lighthouse? Well, doing the same routine over and over again can get boring, but I remember the afternoons when I would pull out my chair, sit in front of the sea with my pipe, and watch the calm water.
Acosta sighs as he plays with his fingers on the chair. There is a short pause.
J. Acosta
I remember it with affection, really.
E. Eiros
I see, I have heard that you had several strange experiences during your stay at the lighthouse, could you tell me about those events?
Acosta looks disconcerted at the researcher, looks nervous, and plays with the ring on his annular finger.
E. Eiros
If you don't like the question, we can skip it if you don't mind-.
J. Acosta
No, it's fine, let's continue.
E. Eiros
Fine with me then.
J. Acosta
Okay, well, you probably already know what people say around town about my stories. They don't want to listen to me because they haven't seen what I've seen. Will you at least listen to me?
E. Eiros
Believe me, I've seen a lot of things in this life, that's why I came to interview you.
J. Acosta
Thank goodness.
Acosta slowly gets up with the help of Researcher Eiros, takes her to a bookshelf, and begins to search through folders, until he finds what appears to be an old sketchbook. “1970 -1972” is engraved in black letters on the front cover.
E. Eiros
Oh, I didn't know you were a sketch artist.
J. Acosta

Illustration of SCP-6710 by Jacobo Acosta.
I learned a few in school. Then I took advantage of my free time to improve a little more. Come, look here.
Acosta shows page 16 to Researcher Eiros. A series of sketches showing SCP-6710 performing different actions can be seen, a scan of a page from the original book is attached next.
E. Eiros
It is a very nice cat.
J. Acosta
When it's the only company you have, you learn to detail it as he deserves.
E. Eiros
But how did you and the cat meet?
J. Acosta
Oh, one night he came in and stared at the lighthouse. I was awake and went out to observe the stars, I had not slept well for several days. He was there, still among the clouds, his eyes were looking at me, or looking at the lighthouse, I can no longer remember with precision.
E. Eiros
What was his attitude towards you?
J. Acosta
Oh, he just stared at me for a long moment and then turned to look at an approaching ship.
E. Eiros
That's all?
J. Acosta
He was always a very calm cat. Although he sometimes liked to play with the water. When there were large shoals near the surface, it would stick its small boat-sized paw in and stir the waters.
Acosta sighs and looks at the illustrations in his hands. There is silence for a couple of minutes.
J. Acosta
Sometimes I go out into the street on holidays, when children run wild and music is loud. I see the clouds and look for him among them.
He runs a hand over the notebook, his finger stills on the drawing that most closely details the feline's face. A few seconds pass in silence.
J. Acosta
I haven't found him for years.
E. Eiros
I see, I hope someday you can meet again. Did you ever try to communicate with him?
J. Acosta
The cat? Oh of course not, I was just passing the time watching him. When I drew him jumping through the clouds, he just turned for a moment to look at me, waved his paw at me, and jumped away. Sometimes he made noises and what noises! When he meowed, you felt the whole place vibrate, you could even see the clouds move. It was a bit impressive, but you got used to it.
E. Eiros
Curious, one would expect something more…spectacular.
J. Acosta
It was no big deal.
Acosta carefully closes the sketchbook.
J. Acosta
But he was a good cat.
E. Eiros
Nothing strange happened, something to let you know what the cat was?
Interviewed softly taps his chin with the edge of the sketchbook.
J. Acosta
E. Eiros
Perhaps some sort of reaction to fear?
J. Acosta
I don't know, he looked more tired than usual. And it was the first time I saw his claws.
E. Eiros
Quite interesting.
Acosta offers the sketchbook to Researcher Eiros.
J. Acosta
Here, it will be useful for your research. Just take good care of it, please.
E. Eiros
Thank you very much, Mr. Acosta. To conclude, when was the last time you saw him?
J. Acosta
I never knew when the last time was, he just stopped showing up one day and I didn't think much about it until now. When I was removed from the position, I swear I could see him out of the corner of my eye, a single instant, a moment that I keep in my memory very strongly.
Acosta invites researcher Eiros to a cup of mate, the rest of the conversation was omitted due to superfluous data.
Closing Statement

View of Les Éclaireurs Lighthouse before the appearance of SCP-6710.
Class B amnestics were administered to Jacobo Acosta, the individual's usefulness for future research has been discarded due to his advanced age. Researcher Ema Eiros has proposed to begin a search protocol for other subjects who have had similar contact with SCP-6710. The Mobile Task Force Delta-9 has been assigned to this task.
Other attempts to find subjects related to the anomaly have not yielded conclusive results.
[08:32] Les Éclaireurs lighthouse can be seen a few meters away, the camera is on a remotely operated buoy, there is no unusual activity.
[08:42] A cloud cluster begins to form near the mountains as seen from the camera.
[08:45] SCP-6710 appears among the clouds, looks to his sides, and moves in the direction of the lighthouse, only the front part of his body is visible, the rest is hidden among the clouds.
[08:57] The feline entity stands in front of the lighthouse, stares at it for 8 minutes.
[09:05] SCP-6710 emits an ascending vocalization over a short time in the direction of the lighthouse3. Repeat the sound for several minutes while observing the surroundings of the lighthouse.
[09:12] SCP-6710 descends to sea level, only the front part of the entity is still observable.
[09:14] SCP-6710 begins to meow intensely, his paws partially submerged in the water, but he doesn't seem to notice. He continues to observe the surroundings of the lighthouse.
[09:21] The meowing slows in strength and takes longer and longer to make. The body of the entity continues to submerge in the water.
[09:46] Meowing ceases, legs are fully submerged. SCP-6710 stares at the reflection in the sea.
[09:48] SCP-6710 begins to purr4 loudly, the water around it begins to vibrate with it.
[09:53] The entity is dropped abruptly on its side, a loud splashing sound is heard, and the camera shakes violently.
[10:00] SCP-6710 is still purring.
[10:24] SCP-6710 raises his head and looks briefly at the lighthouse, making a soft mumbling5 and partially submerges again.
[10:30] A strong beam of light begins to surround SCP-6710, leaving the camera unusable, subsequently the entity disappeared.
Closing Statement

Light trail left by SCP-6710 minutes after vanishing.
SCP-6710 has not manifested itself since the incident nor has it shown any signs of appearance. Whether or not this event is related to the death of Jacobo Acosta on August 15, 2013, is still under debate. The classification of the object is proposed to be changed to Neutralized.
