I think that's probable...with a name like Tabitha, which is cat-like...and just looked up that the name is as old as Superman == 1st appearing in Action COmics #1!Tigress seems to be a case of taking a name and building a new character around it. (If indeed they were aware of the DC Tigresses )
(Though I was confused...I was used to the MArvel character, who actually transformed into a cat-like creature..with Gotham you never know...)
