History
Tabby is a cat that was used by Madame Monstrosity in her experiments and was spliced with Tabitha Briggs into a single cat-like Humanimal being. Years later, Spider-Man was able to reverse the process, restoring most humans and animals to their original form.[1] Tabitha kept Tabby as her pet, as due to their years spent as a single being they were still able to understand each other's speech.[2]
