Kitty be like "burn baby burn"
But fun to watch this again,still wonder why everyone thinks that Kitty is weak or need trining in the first place,the girl is crazy,better watch out,just because she doesn't show what she is capable of,that doesn't mean that she is weak,after all I guess you were surprised when you learnt the truth,so let's see if you can learn more in the future .
And one advice,thoses two girls kinda seem a little bit ,like Amy when it comes to how they react ,if you are able to give them their own personalities,and show it in the animation,that would be great

It's a nice throwback to the mid to late 2000s, when Sprite Animations were fairly more prominent, but it also feels a bit stilted and choppy at points.
The animation isn't bad, no, but I do feel like it needs some work to feel a little more lively.
An example of where I feel it could be improved is during the portion of the fight, where they're trading punches with one another.
Instead of the same punch frames being repeated, I'd like to suggest a bit of variety in that they could alternate between left and right hands punching or perhaps the purple hedgehog could throw in a kick and that could clash with the pink hedgehog's fist.

All in all however, this animation is still very nicely done and it makes me feel nostalgic for the internet in the mid to late 2000s.

I miss sprite animations.
