Excellent opening sentence. Grabbed my attention right away.

I loved that I did not have any information about what is going on, or who this zombie is, but I got a personality and setting so easily in my mind. Great storytelling.

You could use a few more commas, though. As a proofreader, the missing commas burn into my soul, but there's no way I could list them all, haha.

And "It’s eyes were huge" is using the wrong its.

"You shall have hte run of my kitchen" has a clear typo, too.

I found this highly amusing from beginning to end, it was a great read.
