Contraindicated in Mouse, Pet Rat, Gerbil, Prairie Dog, Horse (Equine), Cattle / Sheep / Goat, Rabbit, Chinchilla, Hamster, Degu, Guinea Pig
Mouse: Lincosamides cause fatal diarrhea in MousePlumb's states of the lincosamides: "Do NOT give this medicine to horses, cattle, sheep, goats, deer, rabbits, mice, rats, hamsters, or guinea pigs, as it may cause fatal diarrhea," and elsewhere that "the lincosamides are considered contraindicated for use in horses, ruminants, rabbits." The mechanism is the same selective destruction of gram-positive gut flora that kills rabbits. Added 2026-08-11 after an audit found this species unreachable by any token, so this warning could never fire for it.

Rabbit: Oral lincosamides cause fatal dysbiosis in rabbitsSame mechanism as oral beta-lactams — selective destruction of gram-positive hindgut flora. Never administer oral clindamycin or lincomycin to rabbits.
Chinchilla: Oral lincosamides cause fatal dysbiosis in chinchillasClindamycin and lincomycin destroy gram-positive hindgut flora and precipitate fatal Clostridium enterotoxemia in chinchillas. Never administer.
Hamster: Oral lincosamides cause fatal enterocolitis in hamstersClindamycin and lincomycin are among the antibiotics that induce fatal Clostridium difficile enterocolitis in hamsters. Never administer.
Degu: Oral lincosamides risk fatal dysbiosis in degusExtrapolated from chinchillas and guinea pigs (shared caviomorph hindgut physiology): oral clindamycin/lincomycin should be treated as contraindicated in degus.
Guinea Pig: Oral lincosamides cause fatal dysbiosis in guinea pigsClindamycin and lincomycin cause the same fatal Clostridium enterotoxemia in guinea pigs as oral beta-lactams. Never administer.
