Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.

Prototype full mu-opioid receptor agonist. Activates mu, kappa, and delta opioid receptors producing analgesia, sedation, and euphoria.
Histamine release with rapid IV injection (hypotension, bronchoconstriction — give slowly). Vomiting and defecation common initial effects. Respiratory depression. Cats: may cause excitation/dysphoria at higher doses. Controlled substance (Schedule II).
Species-specific contraindications and adverse-reaction reports for rabbits may differ from canine / feline reference data — consult the primary citations listed with each rule.

These are general warnings for Morphine across species; consult the rabbit dosing table above for species-specific guidance. Histamine release with rapid IV injection (hypotension, bronchoconstriction — give slowly). Vomiting and defecation common initial effects. Respiratory depression. Cats: may cause excitation/dysphoria at higher doses. Controlled substance (Schedule II).
Why a species-specific page? Morphine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in rabbits — the rules above are the citations specific to this species, not generic recommendations.
