Yes, I'd prefer that. So make the attacks - and write SA of spinesSince the description doesn't mention them being aggressive, I'm find with just making the spines purely a reflexive SA.
Spines (Ex): When startled or attacked, three spines on the rabbit's stomach become erect. Any creature holding (grappling) a spiny rabbit or otherwise in contact with its stomach at that time must make a DC X Reflex save or take 1 hp damage and be exposed to the rabbit's poison.
