It's fine.

[@Oblivion666] I skimmed over your form and saw an issue. Cats aren't like the cats in Radiant Dawn that grew to a large size. Here, the cats are going to be the size of house cats, more specialized for stealth and espionage than for fighting. We can say that the Cats in RD were actually Leopards due to their big size. 
Neela can still be a feline Laguz if you want her to be.  However, if you want her to be big enough to take down a human when she was just a kitten (which makes me scratch my head, but let's see what Sol says about it), you can make her a cougar or panther Laguz or something.
