it seems every time i get beer in my colony either via making it or buying it if my colony has small animals they will immediately go and drink the beer to the point were at the very least they will get blackout drunk which was the case of one of my modded colony i don't remember the name of the mod i had installed but it makes rabbits breed like well... rabbits i installed it thinking if i tame or buy a male and female rabbit i could breed them for food but any way i had a ton of rabbits in the colony and then i brought about 400 beer from a trade ship my colonists had moved the beer into storage and a day later there was vomit all over the colony and the vast majority of the rabbits were all either hammered or blackout drunk.
in my current colony i brought about 30 - 40 beer and my colonists hadn't had a chance to get the beer in storage yet due to the mass of corpses from a manhunting pack of elephants and a few ingame hours later i get a message saying cockerel 1 has suffered chemical damage then a minute later a bunch of messages saying my chickens of either gender including cockerel 1 had cirrhosis of which cockerel 1 died of a minute later all my other animals my cat, my caribous, my minions, my muffalochicken and my muffalopedes all didn't touch the beer only the chickens so lesson learned: small animals and beer don't mix in rimworld
