[Snake]

Make them get bonus Evasion damage reduction. 5% per 20 SAN. :^)

Jokes aside, Felidae only gets a max of:

+2 Move (at 20 Scaled SAN)
+3 Move (at 40 Scaled SAN)
+4 Move (at 60 Scaled SAN, which requires 69-72 SAN)

with their SAN gimmick. It's fine AND terribly underrated. Wolves bark for damage, fear and hunted, Cats run.
