What you get
Built around the patients other formularies bury in an appendix.
Exotic-first, source-cited
Reptiles, birds, rabbits, ferrets, chinchillas, hedgehogs, rats, guinea pigs, cattle, horses, dogs, and cats — every dose tied back to Carpenter's, Plumb's, peer-reviewed journals, or expert consensus.
Evidence levels on every dose
Strong / Moderate / Weak / Anecdotal / Extrapolated badges next to every number, so you know at a glance whether you're working from a controlled trial or a single case report.
Drug interactions + breed alerts
Pairwise drug-drug interactions plus species-specific contraindications — MDR1 sensitivity, oral β-lactams in rabbits, NSAID warnings — surface automatically before you prescribe.
