Loyalty or obsession?

To her feet I brought mice,

While mounted on her mare I sat birds in offering,

I wanted to be the master's cat.

While reading I'd softly pad up to her purring,

On her bed I would lay flat and wait to be pet,

I wanted to be the master's cat.

Not once did I mew for food, I got it on my own,

My tummy almost always empty,

I wanted to be the master's cat.

One day she found it to read, so upon her feet I curled up,

My hunger strong, my will to live gone,

I simply purred myself to sleep,

I wanted to be the master's cat.
