Item #: SCP-XXXX
Object Class: Keter
Special Containment Procedures: Due to the scale and nature of SCP-XXXX, it cannot be contained. Instead, the anomalous entities it manifests, SCP-XXXX-1, are to be secured to limit the impact of the anomaly.
As many instances of SCP-XXXX-1 live with civilians, disinformation papers are to be published in well-regarded biology and animal behavior journals to provide a false explanation for the true nature of SCP-XXXX-1-L.
Regions known to or are expected to experience SCP-XXXX are to be monitored for newly manifested instances of SCP-XXXX-1. Upon detection, a joint task force consisting of members of Mobile Task Forces Sigma-88 (“Animal Control”) and Beta-4 (“Castaways”) are to be sent to said region in order to secure any SCP-XXXX-1 possible and amnestize civilians that have seen the manifestation of SCP-XXXX-1.
To aid in this process, retrieval team members are to be equipped with airtight animal control nets, low-power laser pointers, and nepetalactone1 aerosol sprays. For a comprehensive list of equipment, see Document XXXX/Equipment. Standard animal control tools are ineffectual and thus are not to be used.
Transport of captured SCP-XXXX-1 instances must be done using specialized sealed plastic cages or bags. These containers are to have ventilation openings on the top, but must remain upright at all times in order to prevent potential containment breaches.
Captured instances of SCP-XXXX-1 are to be transferred to an available room of Secure Shelter-XXXX, located near Site-64. All such containment chambers must be hermetically sealed when their corresponding entrances are closed, excluding ceiling ventilation openings. The chambers are to be furnished with adequate bedding, feeding bowls, and standard Foundation-issued litter boxes. For a full list of possible furnishings, see Document XXXX/Furnishings.
On-site GoI-466 (Wilson’s Wildlife Solutions) employees are responsible for cleaning Secure Shelter-XXXX and caring for captured SCP-XXXX-1, as well as ensuring they are sufficiently socialized and adjusted to the presence of humans.
Foundation staff members with Level 2 Clearance and D-class personnel in good standing are allowed interaction with SCP-XXXX-1 in captivity.
[REDACTED], after manifestation of SCP-XXXX
Description: SCP-XXXX is an anomalous meteorological phenomenon that occurs in locations that experience heavy rain or snowfall. SCP-XXXX takes the form of the type of precipitation most common to the region of occurence. Over the course of SCP-XXXX, anomalous animals are generated in areas that accumulate significant quantities of rainwater, ice, or snow. These animals, referred to as SCP-XXXX-1, are universally of the biological genus Felis, with 98% of discovered instances being part of the subspecies Felis catus (the domestic cat).
SCP-XXXX-1 are biologically and behaviorally identical to their non-anomalous counterparts. Most observed instances have been of mild temperament, and are usually friendly towards humans. Furthermore, SCP-XXXX-1 are capable of producing viable offspring with both other instances of SCP-XXXX-1 as well as non-anomalous cats, although said offspring do not have SCP-XXXX-1’s anomalous trait.
SCP-XXXX-1’s anomalous property is their ability to instantaneously undergo a state-shift, turning parts of (or the entirety of) their bodies into a liquid at will. In their liquid state, referred to as SCP-XXXX-1-L, an instance will continue to perform biological and neurological functions. The instance also gains a high degree of motility, despite their lack of solid bones and musculature.
The shift into SCP-XXXX-1-L primarily occurs when an instance attempts to enter confined spaces otherwise impossible for them to fit in while in their solid state. However, this trait is sometimes activated reflexively when SCP-XXXX-1 is startled, suggesting it is used as a defense mechanism, as SCP-XXXX-1-L is immune to most physical harm (as, in that form, they are unaffected by jagged or sharp objects introduced into their liquid bodies).
Qualitatively, SCP-XXXX-1-L has the same color as the external surface of their non-liquid form. Tests have indicated that, tactilely, SCP-XXXX-L have a similar texture to their non-liquid counterparts; instances with fur feel as if they have fur while a liquid. Likewise, ones that lack external body hair feel similar to their normal skin while a liquid. Perceived tactile texture (i.e. hair length or hair density) can be modified via grooming of SCP-XXXX-1 while in their solid state.
While specific values vary between different instances, SCP-XXXX-1-L have a density approximately 80% greater than the average domestic cat at standard temperature and pressure. Instances’ dynamic viscosity is also variable, but is usually on the scale of 10-1 to 101 N s/m2, between the viscosity of olive oil and liquid honey. Moreover, SCP-XXXX-1-L have extremely high cohesion and little adhesion. This prevents both the loss of liquid while moving and mixture with other fluids, resulting in SCP-XXXX-1-L staying a single cohesive mass.
The aforementioned immiscibility applies to multiple instances of SCP-XXXX-1-L as well; when two or more instances make contact, they remain separate and distinct fluids, with no inter-cat mixture.
Currently, extensive testing is eagerly being done on SCP-XXXX-1-L by the Foundation’s Physics, Mathematics, and Zoological Departments.
Addendum: On March 1st, 2019, a large scale containment breach of SCP-XXXX-1 occurred, despite all doors being sealed. However, a majority of the instances were recovered, as they remained in close vicinity to Secure Shelter-XXXX. Most instances were found sleeping on the roof of the facility, or those of nearby structures. Searches for the remaining instances are currently ongoing.
Researcher's Note:
"We appear to have a problem. If you are working near Site-64 and have any sort of cat-related allergies… it's best you stay far away from Shelter-XXXX, and the surrounding region."
