The most serious problem you have with this is that it seems like you've obsessed over the detail of how this thing works, but in doing so you've both failed to actually tell the audience what it does, and also muddied the explanation siginificantly with the details to the point where it becomes difficult to comprehend what you're saying.
The other thing is that your containment procedures are very sparse. You really need to bulk them out, because there are some obvious facets of containment that aren't being addressed.
I think that, as it stands, the article could work as a MC&D object. They've previously been known to work in the whole 'horrifying novelty pets' business (SCP-1575 mentions a whole facility, 'The Miracle Farm' used for this purpose), although I doubt they created it themselves, as they are more into exploitation and resale than research and development. They would most likely have stolen it from somewhere else, perhaps even Prometheus Labs.
I also spotted the connection to SCP-889, but you could work around that, since there are clearly differences between the two ideas. However, you'd have to read through that article and work out a way to place the emphasis of the article on something other than just the results.
A test log might be interesting, and provide your article with some meat, but again you would have to be careful to avoid cutting too close the test log from SCP-889.
Finally, there are some parts of this article where your tone and the fluency of your sentences are a little off. If you like I can go through and see if I can edit some of the phrases for better tone without trying to change the actual message of the sentences for you.
