Stories that play around with consciousness and memory loss are always freighted with serious potential for horror. Had the goats been any hungrier, this story could have been slotted over to Pseudopod, with the two left in the apartment drooling and crawling, having forgotten how to walk or speak.
I personally have issues with this tale, though not on any stylistic premise. I'm not sure I can outline it in this limited space, but here goes.
Fantasy, SciFi...SpecFic in general has two obvious roads it can choose to follow. In the first case, the type I prefer, it can use technology or fantastic setting to outline certain new or interesting challenges to human society, but the answers people find to their problems are within themselves and society, not the technology or magic. The second and in my opinion more common type of SpecFic uses magic and/or tech as its own solution. This is basic Deus ex Machina, and its usage is as old as speculative fiction:like the original mythological Greek plays of Aeschylus and Euripides, (we get the term from the 'mechane;' a wooden crane which was used to wheel out actors dressed like gods over the stage so they could make their final pronouncements.)
I think this story tries to belong to the first category but is dangerously close to being the second. Because of how obvious the goats' influence is made, the message that could be taken away is: 'don't learn to deal with your problems, just get some magical sorrow-devouring pets.' I don't think that was the intent of the story. I don't know how, given the central premise of the story, this could be communicated any better.
As it is, meh.
