Leslie wasn't Dr. Novikoff's first zombie, before her there were sadly a few failed attempts (wouldn't make sense for him to get it right the first time right?)... But then he finally resurrected a calico cat named Trisha, but he waited too long so her body wasn't in a good condition. They spent a number of months together, but Dr. Novikoff wasn't able to reunite her with her family.

They enjoyed their time together. But no matter how hard Dr. Novikoff would try to preserve her body, he could never reverse her decay. Upon her request, he rid her of her consciousnesses.

Dr. Novikoff and Cyrus were almost like the family Trisha never remembered she had....
