After a bit of a rocky start https://www.furaffinity.net/view/56799751/ Danielle and Sasha were getting along marvelously.
The cat and rat duo had just made a major scientific breakthrough, which would be unveiled soon to the feisty little feline's family...

But for now these little ladies were celebrating with some red velvet cake. Provided the big kitty can keep her appetite on the red velvet, rather than Sasha's cake.
The little rat had put on a few ounces since coming to work here, hopefully Danielle isn't trying to fatten her up her tiny girlfriend as a potential rat snack.


And to copy a line from the artist's description: "Sasha's thighs are a bit big, but She has them New York Rat thighs; She could de-rail a train by simply being on the tracks by mistake."
A line which is infinitely better than any joke I could make here.
