Right now, the jury is out on how good this option is. Because for 150 FB Credits, you can just get a cat with features you do like, and perform your own mix-and-match for free, which is what the game is set up for anyway.
I think Crowdstar would've made more people happy and still made some money if they put the Crowdstar Cat up for sale, instead of re-releasing for free it to promote their Gamebar. (Not that I'm complaining about that! Cause I'm glad I got a second chance at it.) it might even be better if they gave this option for horses or dinosaurs. They're so new, there's currently a dearth of designs for those animals.
