I love the firmness!! Give it a really good load and you can make the perfect cat ear shape or use the peak of the sponge to dab on some hair strokes between the ears.
My butterfly wings come out the perfect shape. Get the sponge nice and wet but not too wet and the shapes come out effortless. LOVE THEM

I got the sponges, and although they are not as dense as i like, they are ok. They don't hold water that well, but i can get them to work. I prefer a more dense spongeif possible.
