Day 183 of my captivity... My captors continued to taunt me with
Bizarre little dangling objects. They dine lavishly on fresh meat,
While I am forced to eat dry cereal.  The only thing that keeps me
Going is the hope of escape, and the mild satisfaction that I get from
Clawing their furniture. 
 
Tomorrow I will eat another houseplant.  Today my attempt to kill my
Captors by weaving around their feet while they were walking almost
Succeeded - must try this at the top of the stairs. 
 
In an attempt to disgust and repulse these vile oppressors, I once
Again induced myself to vomit on their favorite chair. I must remember
To try this on their bed. 
 
Decapitated a mouse and brought them the headless body in an attempt to
Make them aware of what I am capable of and to try to strike fear in
Their hearts. They only cooed and condescended about what a good little
Cat I was. Hmmm, that did not work according to plan... 
 
There was some sort of gathering of their accomplices. I was placed in
Solitary throughout the event. However, I could hear the noise and
Smell the food. More important, I overheard that my confinement was due
To my powers of inducing "allergies."  I must learn what this is and
How I may use it to my advantage.
I am convinced the other captives are flunkies and maybe snitches. 
 
The dog is routinely released and seems more than happy to return. He
Is obviously a half-wit. The bird, on the other hand, has got to be an
Informant and speaks with them regularly. I am certain he reports my
Every move. Due to his current placement in the metal room, his safety
Is assured. But I have patience, I can wait, it is only a matter of
Time...
