Well you could just copy paste most of the stuff, with only adjective changes.
"Your legs crack and bend, shifting into a more bulky, sturdy pair of feline legs. You have lion legs."
"Your legs crack and bend, shifting into a more slim, wiry pair of feline legs. You have cheetah legs."
Otherwise, it could just be depending on your fur patterns/colors, with a lion mane overriding stripes for a liger. One big cat TF, with a sub-option to add a mane. Like a medical syringe crossed with one of those multi colored pens.
EDIT: I just realized, you could just use that as the TF, with five options.
Lion makes you taller and slimmer/fitter, and gives you a mane.
Tiger makes you taller and wider (curvy tigers, mmmm), plus the stripes of course.
Leopard doesn't change height or anything, but you do get thick fur if you pick snow leopard (another sub-option, ech, I know).
Cheetah makes you slightly short and slim.
Bob cat could be another. This one makes you slightly shorter, and wider, as well as gives you the cute little ears.
