Bender's guinea pig

Bender had a guinea pig. The guinea pig died prior to the events of "In-A-Gadda-Da-Leela", possibly due to Bender's explosion or rebirthing in the previous episode. Bender is noticeably saddened by its death. It is possible that it is the same guinea pig in Anthology of Interest I, which they use to capture Dr. Zoidberg.
