Cats suffering from greeblingz typically have wild-eyed expressions. A very few cats are naturally immune. Treatment None known. Anti-epileptics are ineffective as the condition appears unrelated to other forms of seizure. Avoid getting in the way of a cat engaged in greebling hunting.
Attacks usually subside spontaneously, perhaps as greeblingz return to their own dimension.
These irritating creatures are not visible to human eyes, but no doubt the superior sight and hearing of cats enables them to see them. If we ever do end up acting just like rats or Pavlov's dogs, it will be largely because behaviorism has conditioned us to do so. All rights reserved.
