Bertha was a female she-cat of the Friesian Redhair breed. She was born on October 1986 and she was sterlied and naive and investigated contact to Joker, a old white cat and the only priest of the Claudandus sect. Claudandus, a Havana Brown cat who murdered her as a 332nd murder victim and after he tries a she-cat of the new-old Felidae breed named Tragiyahn to really copulate with a male cat and when she had killed Pascha, Pascal was not able to presuade her. Claudandus recorded his name and the time of his death on all with the victims and then spent his corpse probably in the catacombs to Jesaja, a Persian cat and the Guardian of the Dead.
Since Bertha is killed by Pascal, one can really assume that she wanted to meet a member of the grown and secret new-old Felidae breed.
