With the cat nature I just thought it would be a nice touch if a felar had some sort of insight into plants. I know our cat knows exactly what to eat when it got stomach problems. It wouldn't really affect game balance, but I can understand if other things have higher priority.

Felar aren't entirely natural creatures - (See HELP FELAR). Additionally, the great cats from which they are magically descended are more likely to be carnivorous predators rather than a housecat munching on the back lawn when it feels sick.

Also, I think felar as a race are sitting pretty in terms of catlike perks and abilities. If we were to add something though, it is highly unlikely to be a plant-munching ability.

If you'd like to play a felar with some insight into the local flora, try a ranger!

If descended from predators, could make the argument that felars should be able to eat "guts" bodyparts without becoming poisoned. Obviously not...uh...a big deal.
